Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465722, here are decompositions:

11 + 31465711 = 31465722
59 + 31465663 = 31465722
61 + 31465661 = 31465722
73 + 31465649 = 31465722
103 + 31465619 = 31465722
151 + 31465571 = 31465722
193 + 31465529 = 31465722
241 + 31465481 = 31465722

Showing the first eight; more decompositions exist.
