Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456916, here are decompositions:

13 + 31456903 = 31456916
67 + 31456849 = 31456916
97 + 31456819 = 31456916
277 + 31456639 = 31456916
487 + 31456429 = 31456916
823 + 31456093 = 31456916
1039 + 31455877 = 31456916
1087 + 31455829 = 31456916

Showing the first eight; more decompositions exist.
