Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614718, here are decompositions:

11 + 31614707 = 31614718
17 + 31614701 = 31614718
41 + 31614677 = 31614718
71 + 31614647 = 31614718
131 + 31614587 = 31614718
167 + 31614551 = 31614718
269 + 31614449 = 31614718
347 + 31614371 = 31614718

Showing the first eight; more decompositions exist.
