Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626310, here are decompositions:

101 + 31626209 = 31626310
113 + 31626197 = 31626310
179 + 31626131 = 31626310
257 + 31626053 = 31626310
269 + 31626041 = 31626310
347 + 31625963 = 31626310
461 + 31625849 = 31626310
467 + 31625843 = 31626310

Showing the first eight; more decompositions exist.
