Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514366, here are decompositions:

127 + 31514239 = 31514366
223 + 31514143 = 31514366
307 + 31514059 = 31514366
379 + 31513987 = 31514366
409 + 31513957 = 31514366
439 + 31513927 = 31514366
487 + 31513879 = 31514366
523 + 31513843 = 31514366

Showing the first eight; more decompositions exist.
