Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466630, here are decompositions:

3 + 31466627 = 31466630
43 + 31466587 = 31466630
67 + 31466563 = 31466630
127 + 31466503 = 31466630
229 + 31466401 = 31466630
241 + 31466389 = 31466630
367 + 31466263 = 31466630
373 + 31466257 = 31466630

Showing the first eight; more decompositions exist.
