Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529310, here are decompositions:

31 + 31529279 = 31529310
37 + 31529273 = 31529310
41 + 31529269 = 31529310
53 + 31529257 = 31529310
61 + 31529249 = 31529310
67 + 31529243 = 31529310
97 + 31529213 = 31529310
223 + 31529087 = 31529310

Showing the first eight; more decompositions exist.
