Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597706, here are decompositions:

13 + 31597693 = 31597706
67 + 31597639 = 31597706
103 + 31597603 = 31597706
157 + 31597549 = 31597706
199 + 31597507 = 31597706
223 + 31597483 = 31597706
463 + 31597243 = 31597706
577 + 31597129 = 31597706

Showing the first eight; more decompositions exist.
