Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597248, here are decompositions:

5 + 31597243 = 31597248
17 + 31597231 = 31597248
71 + 31597177 = 31597248
97 + 31597151 = 31597248
127 + 31597121 = 31597248
149 + 31597099 = 31597248
167 + 31597081 = 31597248
197 + 31597051 = 31597248

Showing the first eight; more decompositions exist.
