Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624684, here are decompositions:

11 + 31624673 = 31624684
23 + 31624661 = 31624684
41 + 31624643 = 31624684
53 + 31624631 = 31624684
71 + 31624613 = 31624684
137 + 31624547 = 31624684
173 + 31624511 = 31624684
227 + 31624457 = 31624684

Showing the first eight; more decompositions exist.
