Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467518, here are decompositions:

37 + 31467481 = 31467518
151 + 31467367 = 31467518
337 + 31467181 = 31467518
349 + 31467169 = 31467518
541 + 31466977 = 31467518
619 + 31466899 = 31467518
661 + 31466857 = 31467518
727 + 31466791 = 31467518

Showing the first eight; more decompositions exist.
