Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514186, here are decompositions:

37 + 31514149 = 31514186
43 + 31514143 = 31514186
73 + 31514113 = 31514186
127 + 31514059 = 31514186
163 + 31514023 = 31514186
199 + 31513987 = 31514186
229 + 31513957 = 31514186
307 + 31513879 = 31514186

Showing the first eight; more decompositions exist.
