Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467446, here are decompositions:

13 + 31467433 = 31467446
79 + 31467367 = 31467446
277 + 31467169 = 31467446
313 + 31467133 = 31467446
379 + 31467067 = 31467446
457 + 31466989 = 31467446
547 + 31466899 = 31467446
727 + 31466719 = 31467446

Showing the first eight; more decompositions exist.
