Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595226, here are decompositions:

7 + 31595219 = 31595226
17 + 31595209 = 31595226
37 + 31595189 = 31595226
53 + 31595173 = 31595226
163 + 31595063 = 31595226
167 + 31595059 = 31595226
227 + 31594999 = 31595226
239 + 31594987 = 31595226

Showing the first eight; more decompositions exist.
