Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510602, here are decompositions:

29 + 31510573 = 31510602
41 + 31510561 = 31510602
61 + 31510541 = 31510602
113 + 31510489 = 31510602
199 + 31510403 = 31510602
239 + 31510363 = 31510602
281 + 31510321 = 31510602
283 + 31510319 = 31510602

Showing the first eight; more decompositions exist.
