Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456676, here are decompositions:

7 + 31456669 = 31456676
37 + 31456639 = 31456676
79 + 31456597 = 31456676
397 + 31456279 = 31456676
439 + 31456237 = 31456676
457 + 31456219 = 31456676
577 + 31456099 = 31456676
673 + 31456003 = 31456676

Showing the first eight; more decompositions exist.
