Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614820, here are decompositions:

23 + 31614797 = 31614820
113 + 31614707 = 31614820
173 + 31614647 = 31614820
179 + 31614641 = 31614820
233 + 31614587 = 31614820
257 + 31614563 = 31614820
269 + 31614551 = 31614820
443 + 31614377 = 31614820

Showing the first eight; more decompositions exist.
