Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31490354, here are decompositions:

3 + 31490351 = 31490354
31 + 31490323 = 31490354
67 + 31490287 = 31490354
73 + 31490281 = 31490354
97 + 31490257 = 31490354
127 + 31490227 = 31490354
223 + 31490131 = 31490354
277 + 31490077 = 31490354

Showing the first eight; more decompositions exist.
