Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601298, here are decompositions:

31 + 31601267 = 31601298
107 + 31601191 = 31601298
199 + 31601099 = 31601298
257 + 31601041 = 31601298
439 + 31600859 = 31601298
499 + 31600799 = 31601298
557 + 31600741 = 31601298
577 + 31600721 = 31601298

Showing the first eight; more decompositions exist.
