Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565324, here are decompositions:

31 + 31565293 = 31565324
67 + 31565257 = 31565324
103 + 31565221 = 31565324
127 + 31565197 = 31565324
151 + 31565173 = 31565324
157 + 31565167 = 31565324
223 + 31565101 = 31565324
277 + 31565047 = 31565324

Showing the first eight; more decompositions exist.
