Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529338, here are decompositions:

17 + 31529321 = 31529338
59 + 31529279 = 31529338
89 + 31529249 = 31529338
251 + 31529087 = 31529338
257 + 31529081 = 31529338
587 + 31528751 = 31529338
641 + 31528697 = 31529338
839 + 31528499 = 31529338

Showing the first eight; more decompositions exist.
