Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31512332, here are decompositions:

43 + 31512289 = 31512332
73 + 31512259 = 31512332
79 + 31512253 = 31512332
211 + 31512121 = 31512332
223 + 31512109 = 31512332
463 + 31511869 = 31512332
619 + 31511713 = 31512332
829 + 31511503 = 31512332

Showing the first eight; more decompositions exist.
