Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466632, here are decompositions:

3 + 31466629 = 31466632
5 + 31466627 = 31466632
83 + 31466549 = 31466632
251 + 31466381 = 31466632
383 + 31466249 = 31466632
569 + 31466063 = 31466632
653 + 31465979 = 31466632
971 + 31465661 = 31466632

Showing the first eight; more decompositions exist.
