Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466688, here are decompositions:

17 + 31466671 = 31466688
31 + 31466657 = 31466688
59 + 31466629 = 31466688
61 + 31466627 = 31466688
101 + 31466587 = 31466688
139 + 31466549 = 31466688
307 + 31466381 = 31466688
347 + 31466341 = 31466688

Showing the first eight; more decompositions exist.
