Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594544, here are decompositions:

43 + 31594501 = 31594544
151 + 31594393 = 31594544
193 + 31594351 = 31594544
211 + 31594333 = 31594544
271 + 31594273 = 31594544
307 + 31594237 = 31594544
463 + 31594081 = 31594544
601 + 31593943 = 31594544

Showing the first eight; more decompositions exist.
