Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614670, here are decompositions:

23 + 31614647 = 31614670
29 + 31614641 = 31614670
83 + 31614587 = 31614670
107 + 31614563 = 31614670
293 + 31614377 = 31614670
317 + 31614353 = 31614670
443 + 31614227 = 31614670
491 + 31614179 = 31614670

Showing the first eight; more decompositions exist.
