Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31490464, here are decompositions:

3 + 31490461 = 31490464
11 + 31490453 = 31490464
17 + 31490447 = 31490464
101 + 31490363 = 31490464
113 + 31490351 = 31490464
167 + 31490297 = 31490464
227 + 31490237 = 31490464
521 + 31489943 = 31490464

Showing the first eight; more decompositions exist.
