Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456608, here are decompositions:

11 + 31456597 = 31456608
19 + 31456589 = 31456608
61 + 31456547 = 31456608
107 + 31456501 = 31456608
167 + 31456441 = 31456608
179 + 31456429 = 31456608
229 + 31456379 = 31456608
277 + 31456331 = 31456608

Showing the first eight; more decompositions exist.
