Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594224, here are decompositions:

31 + 31594193 = 31594224
61 + 31594163 = 31594224
73 + 31594151 = 31594224
127 + 31594097 = 31594224
163 + 31594061 = 31594224
241 + 31593983 = 31594224
271 + 31593953 = 31594224
281 + 31593943 = 31594224

Showing the first eight; more decompositions exist.
