Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486702, here are decompositions:

41 + 31486661 = 31486702
59 + 31486643 = 31486702
89 + 31486613 = 31486702
131 + 31486571 = 31486702
173 + 31486529 = 31486702
239 + 31486463 = 31486702
251 + 31486451 = 31486702
311 + 31486391 = 31486702

Showing the first eight; more decompositions exist.
