Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529904, here are decompositions:

5 + 31529899 = 31529904
13 + 31529891 = 31529904
23 + 31529881 = 31529904
61 + 31529843 = 31529904
223 + 31529681 = 31529904
227 + 31529677 = 31529904
233 + 31529671 = 31529904
281 + 31529623 = 31529904

Showing the first eight; more decompositions exist.
