Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494176, here are decompositions:

19 + 31494157 = 31494176
79 + 31494097 = 31494176
97 + 31494079 = 31494176
193 + 31493983 = 31494176
277 + 31493899 = 31494176
397 + 31493779 = 31494176
433 + 31493743 = 31494176
487 + 31493689 = 31494176

Showing the first eight; more decompositions exist.
