Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466656, here are decompositions:

29 + 31466627 = 31466656
59 + 31466597 = 31466656
107 + 31466549 = 31466656
269 + 31466387 = 31466656
449 + 31466207 = 31466656
593 + 31466063 = 31466656
653 + 31466003 = 31466656
677 + 31465979 = 31466656

Showing the first eight; more decompositions exist.
