Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466758, here are decompositions:

5 + 31466753 = 31466758
101 + 31466657 = 31466758
131 + 31466627 = 31466758
431 + 31466327 = 31466758
467 + 31466291 = 31466758
509 + 31466249 = 31466758
929 + 31465829 = 31466758
977 + 31465781 = 31466758

Showing the first eight; more decompositions exist.
