Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466948, here are decompositions:

127 + 31466821 = 31466948
157 + 31466791 = 31466948
199 + 31466749 = 31466948
229 + 31466719 = 31466948
241 + 31466707 = 31466948
277 + 31466671 = 31466948
547 + 31466401 = 31466948
607 + 31466341 = 31466948

Showing the first eight; more decompositions exist.
