Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31512246, here are decompositions:

37 + 31512209 = 31512246
47 + 31512199 = 31512246
127 + 31512119 = 31512246
137 + 31512109 = 31512246
163 + 31512083 = 31512246
223 + 31512023 = 31512246
229 + 31512017 = 31512246
277 + 31511969 = 31512246

Showing the first eight; more decompositions exist.
