Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529502, here are decompositions:

23 + 31529479 = 31529502
31 + 31529471 = 31529502
71 + 31529431 = 31529502
89 + 31529413 = 31529502
149 + 31529353 = 31529502
181 + 31529321 = 31529502
223 + 31529279 = 31529502
229 + 31529273 = 31529502

Showing the first eight; more decompositions exist.
