Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467892, here are decompositions:

83 + 31467809 = 31467892
173 + 31467719 = 31467892
353 + 31467539 = 31467892
359 + 31467533 = 31467892
383 + 31467509 = 31467892
389 + 31467503 = 31467892
461 + 31467431 = 31467892
503 + 31467389 = 31467892

Showing the first eight; more decompositions exist.
