Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601080, here are decompositions:

3 + 31601077 = 31601080
29 + 31601051 = 31601080
197 + 31600883 = 31601080
257 + 31600823 = 31601080
263 + 31600817 = 31601080
281 + 31600799 = 31601080
347 + 31600733 = 31601080
359 + 31600721 = 31601080

Showing the first eight; more decompositions exist.
