Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466048, here are decompositions:

157 + 31465891 = 31466048
199 + 31465849 = 31466048
307 + 31465741 = 31466048
337 + 31465711 = 31466048
487 + 31465561 = 31466048
631 + 31465417 = 31466048
727 + 31465321 = 31466048
739 + 31465309 = 31466048

Showing the first eight; more decompositions exist.
