Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466662, here are decompositions:

5 + 31466657 = 31466662
113 + 31466549 = 31466662
281 + 31466381 = 31466662
599 + 31466063 = 31466662
659 + 31466003 = 31466662
683 + 31465979 = 31466662
881 + 31465781 = 31466662
1013 + 31465649 = 31466662

Showing the first eight; more decompositions exist.
