Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594308, here are decompositions:

37 + 31594271 = 31594308
61 + 31594247 = 31594308
71 + 31594237 = 31594308
149 + 31594159 = 31594308
157 + 31594151 = 31594308
211 + 31594097 = 31594308
227 + 31594081 = 31594308
269 + 31594039 = 31594308

Showing the first eight; more decompositions exist.
