Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466188, here are decompositions:

137 + 31466051 = 31466188
359 + 31465829 = 31466188
431 + 31465757 = 31466188
461 + 31465727 = 31466188
491 + 31465697 = 31466188
557 + 31465631 = 31466188
569 + 31465619 = 31466188
587 + 31465601 = 31466188

Showing the first eight; more decompositions exist.
