Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465756, here are decompositions:

29 + 31465727 = 31465756
59 + 31465697 = 31465756
83 + 31465673 = 31465756
107 + 31465649 = 31465756
137 + 31465619 = 31465756
227 + 31465529 = 31465756
467 + 31465289 = 31465756
563 + 31465193 = 31465756

Showing the first eight; more decompositions exist.
