Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460636, here are decompositions:

127 + 31460509 = 31460636
139 + 31460497 = 31460636
223 + 31460413 = 31460636
307 + 31460329 = 31460636
373 + 31460263 = 31460636
439 + 31460197 = 31460636
463 + 31460173 = 31460636
499 + 31460137 = 31460636

Showing the first eight; more decompositions exist.
