Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597606, here are decompositions:

3 + 31597603 = 31597606
113 + 31597493 = 31597606
239 + 31597367 = 31597606
269 + 31597337 = 31597606
353 + 31597253 = 31597606
479 + 31597127 = 31597606
563 + 31597043 = 31597606
683 + 31596923 = 31597606

Showing the first eight; more decompositions exist.
