Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597322, here are decompositions:

61 + 31597261 = 31597322
79 + 31597243 = 31597322
109 + 31597213 = 31597322
193 + 31597129 = 31597322
223 + 31597099 = 31597322
241 + 31597081 = 31597322
271 + 31597051 = 31597322
331 + 31596991 = 31597322

Showing the first eight; more decompositions exist.
