Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624924, here are decompositions:

3 + 31624921 = 31624924
17 + 31624907 = 31624924
251 + 31624673 = 31624924
263 + 31624661 = 31624924
281 + 31624643 = 31624924
293 + 31624631 = 31624924
311 + 31624613 = 31624924
467 + 31624457 = 31624924

Showing the first eight; more decompositions exist.
