Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614874, here are decompositions:

23 + 31614851 = 31614874
41 + 31614833 = 31614874
167 + 31614707 = 31614874
173 + 31614701 = 31614874
197 + 31614677 = 31614874
227 + 31614647 = 31614874
233 + 31614641 = 31614874
311 + 31614563 = 31614874

Showing the first eight; more decompositions exist.
