Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467182, here are decompositions:

13 + 31467169 = 31467182
79 + 31467103 = 31467182
193 + 31466989 = 31467182
283 + 31466899 = 31467182
433 + 31466749 = 31467182
463 + 31466719 = 31467182
619 + 31466563 = 31467182
853 + 31466329 = 31467182

Showing the first eight; more decompositions exist.
