Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514276, here are decompositions:

37 + 31514239 = 31514276
127 + 31514149 = 31514276
163 + 31514113 = 31514276
349 + 31513927 = 31514276
397 + 31513879 = 31514276
433 + 31513843 = 31514276
457 + 31513819 = 31514276
853 + 31513423 = 31514276

Showing the first eight; more decompositions exist.
