Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467454, here are decompositions:

17 + 31467437 = 31467454
23 + 31467431 = 31467454
107 + 31467347 = 31467454
251 + 31467203 = 31467454
383 + 31467071 = 31467454
443 + 31467011 = 31467454
461 + 31466993 = 31467454
503 + 31466951 = 31467454

Showing the first eight; more decompositions exist.
