Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614218, here are decompositions:

7 + 31614211 = 31614218
19 + 31614199 = 31614218
37 + 31614181 = 31614218
109 + 31614109 = 31614218
127 + 31614091 = 31614218
157 + 31614061 = 31614218
199 + 31614019 = 31614218
211 + 31614007 = 31614218

Showing the first eight; more decompositions exist.
