Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467846, here are decompositions:

17 + 31467829 = 31467846
37 + 31467809 = 31467846
79 + 31467767 = 31467846
83 + 31467763 = 31467846
127 + 31467719 = 31467846
199 + 31467647 = 31467846
257 + 31467589 = 31467846
307 + 31467539 = 31467846

Showing the first eight; more decompositions exist.
