Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31512914, here are decompositions:

7 + 31512907 = 31512914
73 + 31512841 = 31512914
157 + 31512757 = 31512914
211 + 31512703 = 31512914
241 + 31512673 = 31512914
283 + 31512631 = 31512914
313 + 31512601 = 31512914
463 + 31512451 = 31512914

Showing the first eight; more decompositions exist.
