Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466698, here are decompositions:

5 + 31466693 = 31466698
41 + 31466657 = 31466698
71 + 31466627 = 31466698
101 + 31466597 = 31466698
149 + 31466549 = 31466698
311 + 31466387 = 31466698
317 + 31466381 = 31466698
449 + 31466249 = 31466698

Showing the first eight; more decompositions exist.
