Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494056, here are decompositions:

3 + 31494053 = 31494056
67 + 31493989 = 31494056
73 + 31493983 = 31494056
157 + 31493899 = 31494056
199 + 31493857 = 31494056
277 + 31493779 = 31494056
313 + 31493743 = 31494056
367 + 31493689 = 31494056

Showing the first eight; more decompositions exist.
