Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496460, here are decompositions:

11 + 31496449 = 31496460
19 + 31496441 = 31496460
31 + 31496429 = 31496460
41 + 31496419 = 31496460
43 + 31496417 = 31496460
71 + 31496389 = 31496460
89 + 31496371 = 31496460
131 + 31496329 = 31496460

Showing the first eight; more decompositions exist.
