Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601716, here are decompositions:

5 + 31601711 = 31601716
17 + 31601699 = 31601716
149 + 31601567 = 31601716
227 + 31601489 = 31601716
359 + 31601357 = 31601716
449 + 31601267 = 31601716
617 + 31601099 = 31601716
857 + 31600859 = 31601716

Showing the first eight; more decompositions exist.
