Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597302, here are decompositions:

19 + 31597283 = 31597302
41 + 31597261 = 31597302
59 + 31597243 = 31597302
71 + 31597231 = 31597302
89 + 31597213 = 31597302
103 + 31597199 = 31597302
151 + 31597151 = 31597302
173 + 31597129 = 31597302

Showing the first eight; more decompositions exist.
