Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467976, here are decompositions:

83 + 31467893 = 31467976
167 + 31467809 = 31467976
257 + 31467719 = 31467976
383 + 31467593 = 31467976
389 + 31467587 = 31467976
443 + 31467533 = 31467976
467 + 31467509 = 31467976
479 + 31467497 = 31467976

Showing the first eight; more decompositions exist.
