Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31512926, here are decompositions:

13 + 31512913 = 31512926
19 + 31512907 = 31512926
103 + 31512823 = 31512926
157 + 31512769 = 31512926
223 + 31512703 = 31512926
619 + 31512307 = 31512926
673 + 31512253 = 31512926
727 + 31512199 = 31512926

Showing the first eight; more decompositions exist.
