Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456764, here are decompositions:

23 + 31456741 = 31456764
37 + 31456727 = 31456764
43 + 31456721 = 31456764
61 + 31456703 = 31456764
113 + 31456651 = 31456764
167 + 31456597 = 31456764
233 + 31456531 = 31456764
263 + 31456501 = 31456764

Showing the first eight; more decompositions exist.
