Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594320, here are decompositions:

11 + 31594309 = 31594320
47 + 31594273 = 31594320
73 + 31594247 = 31594320
83 + 31594237 = 31594320
127 + 31594193 = 31594320
157 + 31594163 = 31594320
223 + 31594097 = 31594320
239 + 31594081 = 31594320

Showing the first eight; more decompositions exist.
