Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31490334, here are decompositions:

11 + 31490323 = 31490334
37 + 31490297 = 31490334
47 + 31490287 = 31490334
53 + 31490281 = 31490334
97 + 31490237 = 31490334
107 + 31490227 = 31490334
241 + 31490093 = 31490334
257 + 31490077 = 31490334

Showing the first eight; more decompositions exist.
