Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456696, here are decompositions:

17 + 31456679 = 31456696
107 + 31456589 = 31456696
149 + 31456547 = 31456696
179 + 31456517 = 31456696
317 + 31456379 = 31456696
419 + 31456277 = 31456696
449 + 31456247 = 31456696
503 + 31456193 = 31456696

Showing the first eight; more decompositions exist.
