Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595448, here are decompositions:

41 + 31595407 = 31595448
61 + 31595387 = 31595448
197 + 31595251 = 31595448
211 + 31595237 = 31595448
229 + 31595219 = 31595448
239 + 31595209 = 31595448
271 + 31595177 = 31595448
307 + 31595141 = 31595448

Showing the first eight; more decompositions exist.
