Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597434, here are decompositions:

17 + 31597417 = 31597434
23 + 31597411 = 31597434
67 + 31597367 = 31597434
97 + 31597337 = 31597434
151 + 31597283 = 31597434
173 + 31597261 = 31597434
181 + 31597253 = 31597434
191 + 31597243 = 31597434

Showing the first eight; more decompositions exist.
