Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466658, here are decompositions:

29 + 31466629 = 31466658
31 + 31466627 = 31466658
61 + 31466597 = 31466658
71 + 31466587 = 31466658
109 + 31466549 = 31466658
257 + 31466401 = 31466658
269 + 31466389 = 31466658
271 + 31466387 = 31466658

Showing the first eight; more decompositions exist.
