Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529332, here are decompositions:

11 + 31529321 = 31529332
53 + 31529279 = 31529332
59 + 31529273 = 31529332
83 + 31529249 = 31529332
89 + 31529243 = 31529332
113 + 31529219 = 31529332
251 + 31529081 = 31529332
479 + 31528853 = 31529332

Showing the first eight; more decompositions exist.
