Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467406, here are decompositions:

17 + 31467389 = 31467406
59 + 31467347 = 31467406
239 + 31467167 = 31467406
317 + 31467089 = 31467406
557 + 31466849 = 31467406
647 + 31466759 = 31467406
653 + 31466753 = 31467406
809 + 31466597 = 31467406

Showing the first eight; more decompositions exist.
