Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529362, here are decompositions:

3 + 31529359 = 31529362
41 + 31529321 = 31529362
83 + 31529279 = 31529362
89 + 31529273 = 31529362
113 + 31529249 = 31529362
149 + 31529213 = 31529362
281 + 31529081 = 31529362
509 + 31528853 = 31529362

Showing the first eight; more decompositions exist.
