Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31512304, here are decompositions:

113 + 31512191 = 31512304
191 + 31512113 = 31512304
233 + 31512071 = 31512304
281 + 31512023 = 31512304
293 + 31512011 = 31512304
311 + 31511993 = 31512304
431 + 31511873 = 31512304
491 + 31511813 = 31512304

Showing the first eight; more decompositions exist.
