Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467928, here are decompositions:

17 + 31467911 = 31467928
29 + 31467899 = 31467928
251 + 31467677 = 31467928
281 + 31467647 = 31467928
389 + 31467539 = 31467928
419 + 31467509 = 31467928
431 + 31467497 = 31467928
461 + 31467467 = 31467928

Showing the first eight; more decompositions exist.
