Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559796, here are decompositions:

13 + 31559783 = 31559796
19 + 31559777 = 31559796
97 + 31559699 = 31559796
109 + 31559687 = 31559796
137 + 31559659 = 31559796
157 + 31559639 = 31559796
173 + 31559623 = 31559796
223 + 31559573 = 31559796

Showing the first eight; more decompositions exist.
