Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494416, here are decompositions:

337 + 31494079 = 31494416
433 + 31493983 = 31494416
673 + 31493743 = 31494416
727 + 31493689 = 31494416
739 + 31493677 = 31494416
823 + 31493593 = 31494416
859 + 31493557 = 31494416
883 + 31493533 = 31494416

Showing the first eight; more decompositions exist.
