Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601356, here are decompositions:

89 + 31601267 = 31601356
257 + 31601099 = 31601356
557 + 31600799 = 31601356
653 + 31600703 = 31601356
827 + 31600529 = 31601356
863 + 31600493 = 31601356
947 + 31600409 = 31601356
1049 + 31600307 = 31601356

Showing the first eight; more decompositions exist.
