Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531064, here are decompositions:

7 + 31531057 = 31531064
163 + 31530901 = 31531064
223 + 31530841 = 31531064
421 + 31530643 = 31531064
457 + 31530607 = 31531064
541 + 31530523 = 31531064
577 + 31530487 = 31531064
613 + 31530451 = 31531064

Showing the first eight; more decompositions exist.
