Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456794, here are decompositions:

7 + 31456787 = 31456794
13 + 31456781 = 31456794
53 + 31456741 = 31456794
67 + 31456727 = 31456794
73 + 31456721 = 31456794
197 + 31456597 = 31456794
263 + 31456531 = 31456794
277 + 31456517 = 31456794

Showing the first eight; more decompositions exist.
