Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513324, here are decompositions:

131 + 31513193 = 31513324
137 + 31513187 = 31513324
233 + 31513091 = 31513324
251 + 31513073 = 31513324
317 + 31513007 = 31513324
431 + 31512893 = 31513324
593 + 31512731 = 31513324
641 + 31512683 = 31513324

Showing the first eight; more decompositions exist.
