Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597266, here are decompositions:

5 + 31597261 = 31597266
13 + 31597253 = 31597266
23 + 31597243 = 31597266
53 + 31597213 = 31597266
67 + 31597199 = 31597266
89 + 31597177 = 31597266
137 + 31597129 = 31597266
139 + 31597127 = 31597266

Showing the first eight; more decompositions exist.
