Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566696, here are decompositions:

37 + 31566659 = 31566696
97 + 31566599 = 31566696
107 + 31566589 = 31566696
137 + 31566559 = 31566696
149 + 31566547 = 31566696
173 + 31566523 = 31566696
179 + 31566517 = 31566696
199 + 31566497 = 31566696

Showing the first eight; more decompositions exist.
