Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624654, here are decompositions:

11 + 31624643 = 31624654
23 + 31624631 = 31624654
41 + 31624613 = 31624654
107 + 31624547 = 31624654
197 + 31624457 = 31624654
311 + 31624343 = 31624654
317 + 31624337 = 31624654
641 + 31624013 = 31624654

Showing the first eight; more decompositions exist.
