Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31490336, here are decompositions:

13 + 31490323 = 31490336
37 + 31490299 = 31490336
79 + 31490257 = 31490336
109 + 31490227 = 31490336
313 + 31490023 = 31490336
337 + 31489999 = 31490336
373 + 31489963 = 31490336
457 + 31489879 = 31490336

Showing the first eight; more decompositions exist.
