Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595248, here are decompositions:

5 + 31595243 = 31595248
11 + 31595237 = 31595248
29 + 31595219 = 31595248
59 + 31595189 = 31595248
71 + 31595177 = 31595248
107 + 31595141 = 31595248
227 + 31595021 = 31595248
239 + 31595009 = 31595248

Showing the first eight; more decompositions exist.
