Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514490, here are decompositions:

11 + 31514479 = 31514490
13 + 31514477 = 31514490
17 + 31514473 = 31514490
41 + 31514449 = 31514490
61 + 31514429 = 31514490
67 + 31514423 = 31514490
71 + 31514419 = 31514490
89 + 31514401 = 31514490

Showing the first eight; more decompositions exist.
