Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31490062, here are decompositions:

5 + 31490057 = 31490062
113 + 31489949 = 31490062
179 + 31489883 = 31490062
311 + 31489751 = 31490062
353 + 31489709 = 31490062
389 + 31489673 = 31490062
449 + 31489613 = 31490062
491 + 31489571 = 31490062

Showing the first eight; more decompositions exist.
