Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614628, here are decompositions:

41 + 31614587 = 31614628
179 + 31614449 = 31614628
251 + 31614377 = 31614628
257 + 31614371 = 31614628
401 + 31614227 = 31614628
431 + 31614197 = 31614628
449 + 31614179 = 31614628
467 + 31614161 = 31614628

Showing the first eight; more decompositions exist.
