Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467584, here are decompositions:

13 + 31467571 = 31467584
103 + 31467481 = 31467584
151 + 31467433 = 31467584
283 + 31467301 = 31467584
457 + 31467127 = 31467584
607 + 31466977 = 31467584
691 + 31466893 = 31467584
727 + 31466857 = 31467584

Showing the first eight; more decompositions exist.
