Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595326, here are decompositions:

47 + 31595279 = 31595326
53 + 31595273 = 31595326
83 + 31595243 = 31595326
89 + 31595237 = 31595326
107 + 31595219 = 31595326
137 + 31595189 = 31595326
149 + 31595177 = 31595326
263 + 31595063 = 31595326

Showing the first eight; more decompositions exist.
