Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456316, here are decompositions:

37 + 31456279 = 31456316
79 + 31456237 = 31456316
97 + 31456219 = 31456316
193 + 31456123 = 31456316
223 + 31456093 = 31456316
313 + 31456003 = 31456316
439 + 31455877 = 31456316
457 + 31455859 = 31456316

Showing the first eight; more decompositions exist.
