Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597332, here are decompositions:

71 + 31597261 = 31597332
79 + 31597253 = 31597332
89 + 31597243 = 31597332
101 + 31597231 = 31597332
181 + 31597151 = 31597332
211 + 31597121 = 31597332
233 + 31597099 = 31597332
251 + 31597081 = 31597332

Showing the first eight; more decompositions exist.
