Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494182, here are decompositions:

3 + 31494179 = 31494182
103 + 31494079 = 31494182
193 + 31493989 = 31494182
199 + 31493983 = 31494182
241 + 31493941 = 31494182
283 + 31493899 = 31494182
331 + 31493851 = 31494182
439 + 31493743 = 31494182

Showing the first eight; more decompositions exist.
