Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466722, here are decompositions:

3 + 31466719 = 31466722
29 + 31466693 = 31466722
173 + 31466549 = 31466722
431 + 31466291 = 31466722
659 + 31466063 = 31466722
719 + 31466003 = 31466722
743 + 31465979 = 31466722
941 + 31465781 = 31466722

Showing the first eight; more decompositions exist.
