Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595304, here are decompositions:

31 + 31595273 = 31595304
53 + 31595251 = 31595304
61 + 31595243 = 31595304
67 + 31595237 = 31595304
127 + 31595177 = 31595304
131 + 31595173 = 31595304
163 + 31595141 = 31595304
241 + 31595063 = 31595304

Showing the first eight; more decompositions exist.
