Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601026, here are decompositions:

3 + 31601023 = 31601026
167 + 31600859 = 31601026
227 + 31600799 = 31601026
293 + 31600733 = 31601026
503 + 31600523 = 31601026
617 + 31600409 = 31601026
719 + 31600307 = 31601026
983 + 31600043 = 31601026

Showing the first eight; more decompositions exist.
