Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31512414, here are decompositions:

5 + 31512409 = 31512414
67 + 31512347 = 31512414
71 + 31512343 = 31512414
83 + 31512331 = 31512414
107 + 31512307 = 31512414
223 + 31512191 = 31512414
293 + 31512121 = 31512414
331 + 31512083 = 31512414

Showing the first eight; more decompositions exist.
