Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594144, here are decompositions:

11 + 31594133 = 31594144
47 + 31594097 = 31594144
83 + 31594061 = 31594144
191 + 31593953 = 31594144
311 + 31593833 = 31594144
347 + 31593797 = 31594144
503 + 31593641 = 31594144
641 + 31593503 = 31594144

Showing the first eight; more decompositions exist.
