Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523992, here are decompositions:

53 + 31523939 = 31523992
191 + 31523801 = 31523992
239 + 31523753 = 31523992
359 + 31523633 = 31523992
593 + 31523399 = 31523992
683 + 31523309 = 31523992
761 + 31523231 = 31523992
881 + 31523111 = 31523992

Showing the first eight; more decompositions exist.
