Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529746, here are decompositions:

29 + 31529717 = 31529746
179 + 31529567 = 31529746
239 + 31529507 = 31529746
467 + 31529279 = 31529746
503 + 31529243 = 31529746
659 + 31529087 = 31529746
1049 + 31528697 = 31529746
1187 + 31528559 = 31529746

Showing the first eight; more decompositions exist.
