Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617214, here are decompositions:

47 + 31617167 = 31617214
113 + 31617101 = 31617214
137 + 31617077 = 31617214
191 + 31617023 = 31617214
227 + 31616987 = 31617214
263 + 31616951 = 31617214
281 + 31616933 = 31617214
311 + 31616903 = 31617214

Showing the first eight; more decompositions exist.
