Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594464, here are decompositions:

43 + 31594421 = 31594464
71 + 31594393 = 31594464
113 + 31594351 = 31594464
131 + 31594333 = 31594464
191 + 31594273 = 31594464
193 + 31594271 = 31594464
227 + 31594237 = 31594464
271 + 31594193 = 31594464

Showing the first eight; more decompositions exist.
