Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31264, here are decompositions:

5 + 31259 = 31264
11 + 31253 = 31264
17 + 31247 = 31264
41 + 31223 = 31264
71 + 31193 = 31264
83 + 31181 = 31264
113 + 31151 = 31264
173 + 31091 = 31264

Showing the first eight; more decompositions exist.
