Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456326, here are decompositions:

7 + 31456319 = 31456326
47 + 31456279 = 31456326
67 + 31456259 = 31456326
79 + 31456247 = 31456326
89 + 31456237 = 31456326
107 + 31456219 = 31456326
127 + 31456199 = 31456326
163 + 31456163 = 31456326

Showing the first eight; more decompositions exist.
