Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510066, here are decompositions:

59 + 31510007 = 31510066
173 + 31509893 = 31510066
293 + 31509773 = 31510066
317 + 31509749 = 31510066
383 + 31509683 = 31510066
449 + 31509617 = 31510066
509 + 31509557 = 31510066
647 + 31509419 = 31510066

Showing the first eight; more decompositions exist.
