Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466774, here are decompositions:

43 + 31466731 = 31466774
61 + 31466713 = 31466774
67 + 31466707 = 31466774
103 + 31466671 = 31466774
211 + 31466563 = 31466774
271 + 31466503 = 31466774
373 + 31466401 = 31466774
433 + 31466341 = 31466774

Showing the first eight; more decompositions exist.
