beamer â€” making visible a part of an invisible block (theorem)

I have the following problem:

I have a theorem and want to show only one part of it first, without showing the head of the theorem. I tried:

documentclass[11pt]beamer
usethemeMalmoe
usepackage[utf8]inputenc
usepackage[german]babel
usepackage[T1]fontenc
usepackageamsmath
usepackageamsfonts
usepackageamssymb
usepackagegraphicx

begindocument


beginframeA title
onslide<1->Motivational text.
visible<3->
begintheorem
We have that
beginalign*
visible<2->sqrtpi = int_-infty^infty e^-x^2 textd x
endalign*
endtheorem
endframe

enddocument

what I get:
enter image description here

what I want:
enter image description here

EDIT:

the improved code

endframe

enddocument

yields

In this compiler the color #CCCCCC doesnt even seem to fit.

Maybe a bit hacky but one could simply change the colour of the title to hide it:

documentclass[11pt]beamer
usethemeMalmoe

usepackage[T1]fontenc
usepackageamsmath
usepackageamsfonts
usepackageamssymb

Wow! I have not such good imagination and was developing a tikz overlay solution. (+1)

This is a good idea. But unfortunately I use the colortheme seagull. There the Theorem environment has a gray background. I adapted your answer to this insofar that I set the block title color to #CCCCCC. (+1). But the background stays gray of course.

@Falrach If you could make a MWE that demonstrated the problem, I'm sure it can be fixed.

@koleygr Thanks for the vote. Using tikz overlay is actually also a very good idea. If you already have something it might be interesting to post it as an answer - I would surely upvote it!
