Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614826, here are decompositions:

29 + 31614797 = 31614826
149 + 31614677 = 31614826
179 + 31614647 = 31614826
239 + 31614587 = 31614826
263 + 31614563 = 31614826
449 + 31614377 = 31614826
599 + 31614227 = 31614826
647 + 31614179 = 31614826

Showing the first eight; more decompositions exist.
