Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466636, here are decompositions:

7 + 31466629 = 31466636
73 + 31466563 = 31466636
307 + 31466329 = 31466636
349 + 31466287 = 31466636
373 + 31466263 = 31466636
379 + 31466257 = 31466636
463 + 31466173 = 31466636
499 + 31466137 = 31466636

Showing the first eight; more decompositions exist.
