Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466420, here are decompositions:

19 + 31466401 = 31466420
31 + 31466389 = 31466420
79 + 31466341 = 31466420
157 + 31466263 = 31466420
163 + 31466257 = 31466420
199 + 31466221 = 31466420
277 + 31466143 = 31466420
283 + 31466137 = 31466420

Showing the first eight; more decompositions exist.
