Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466958, here are decompositions:

7 + 31466951 = 31466958
59 + 31466899 = 31466958
101 + 31466857 = 31466958
109 + 31466849 = 31466958
137 + 31466821 = 31466958
167 + 31466791 = 31466958
199 + 31466759 = 31466958
227 + 31466731 = 31466958

Showing the first eight; more decompositions exist.
