Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31512934, here are decompositions:

41 + 31512893 = 31512934
107 + 31512827 = 31512934
251 + 31512683 = 31512934
317 + 31512617 = 31512934
347 + 31512587 = 31512934
587 + 31512347 = 31512934
743 + 31512191 = 31512934
773 + 31512161 = 31512934

Showing the first eight; more decompositions exist.
