Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467692, here are decompositions:

103 + 31467589 = 31467692
211 + 31467481 = 31467692
433 + 31467259 = 31467692
463 + 31467229 = 31467692
523 + 31467169 = 31467692
1021 + 31466671 = 31467692
1063 + 31466629 = 31467692
1129 + 31466563 = 31467692

Showing the first eight; more decompositions exist.
