Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466218, here are decompositions:

11 + 31466207 = 31466218
167 + 31466051 = 31466218
239 + 31465979 = 31466218
389 + 31465829 = 31466218
461 + 31465757 = 31466218
491 + 31465727 = 31466218
521 + 31465697 = 31466218
557 + 31465661 = 31466218

Showing the first eight; more decompositions exist.
