Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566796, here are decompositions:

3 + 31566793 = 31566796
47 + 31566749 = 31566796
59 + 31566737 = 31566796
83 + 31566713 = 31566796
137 + 31566659 = 31566796
197 + 31566599 = 31566796
269 + 31566527 = 31566796
347 + 31566449 = 31566796

Showing the first eight; more decompositions exist.
