Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506796, here are decompositions:

3 + 31506793 = 31506796
5 + 31506791 = 31506796
47 + 31506749 = 31506796
53 + 31506743 = 31506796
107 + 31506689 = 31506796
197 + 31506599 = 31506796
227 + 31506569 = 31506796
317 + 31506479 = 31506796

Showing the first eight; more decompositions exist.
