Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595268, here are decompositions:

17 + 31595251 = 31595268
31 + 31595237 = 31595268
59 + 31595209 = 31595268
79 + 31595189 = 31595268
127 + 31595141 = 31595268
167 + 31595101 = 31595268
269 + 31594999 = 31595268
277 + 31594991 = 31595268

Showing the first eight; more decompositions exist.
