Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529874, here are decompositions:

31 + 31529843 = 31529874
157 + 31529717 = 31529874
193 + 31529681 = 31529874
197 + 31529677 = 31529874
223 + 31529651 = 31529874
251 + 31529623 = 31529874
281 + 31529593 = 31529874
307 + 31529567 = 31529874

Showing the first eight; more decompositions exist.
