Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466908, here are decompositions:

41 + 31466867 = 31466908
59 + 31466849 = 31466908
149 + 31466759 = 31466908
251 + 31466657 = 31466908
281 + 31466627 = 31466908
311 + 31466597 = 31466908
359 + 31466549 = 31466908
521 + 31466387 = 31466908

Showing the first eight; more decompositions exist.
