Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31512364, here are decompositions:

5 + 31512359 = 31512364
17 + 31512347 = 31512364
173 + 31512191 = 31512364
251 + 31512113 = 31512364
281 + 31512083 = 31512364
293 + 31512071 = 31512364
347 + 31512017 = 31512364
353 + 31512011 = 31512364

Showing the first eight; more decompositions exist.
