Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601536, here are decompositions:

23 + 31601513 = 31601536
47 + 31601489 = 31601536
179 + 31601357 = 31601536
269 + 31601267 = 31601536
653 + 31600883 = 31601536
677 + 31600859 = 31601536
719 + 31600817 = 31601536
1013 + 31600523 = 31601536

Showing the first eight; more decompositions exist.
