Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456716, here are decompositions:

13 + 31456703 = 31456716
37 + 31456679 = 31456716
47 + 31456669 = 31456716
127 + 31456589 = 31456716
199 + 31456517 = 31456716
229 + 31456487 = 31456716
337 + 31456379 = 31456716
397 + 31456319 = 31456716

Showing the first eight; more decompositions exist.
