Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494116, here are decompositions:

19 + 31494097 = 31494116
37 + 31494079 = 31494116
127 + 31493989 = 31494116
337 + 31493779 = 31494116
373 + 31493743 = 31494116
439 + 31493677 = 31494116
463 + 31493653 = 31494116
523 + 31493593 = 31494116

Showing the first eight; more decompositions exist.
