Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494536, here are decompositions:

67 + 31494469 = 31494536
97 + 31494439 = 31494536
109 + 31494427 = 31494536
379 + 31494157 = 31494536
439 + 31494097 = 31494536
457 + 31494079 = 31494536
547 + 31493989 = 31494536
757 + 31493779 = 31494536

Showing the first eight; more decompositions exist.
