Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466548, here are decompositions:

167 + 31466381 = 31466548
257 + 31466291 = 31466548
569 + 31465979 = 31466548
719 + 31465829 = 31466548
821 + 31465727 = 31466548
887 + 31465661 = 31466548
929 + 31465619 = 31466548
947 + 31465601 = 31466548

Showing the first eight; more decompositions exist.
