Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594506, here are decompositions:

5 + 31594501 = 31594506
17 + 31594489 = 31594506
43 + 31594463 = 31594506
107 + 31594399 = 31594506
113 + 31594393 = 31594506
173 + 31594333 = 31594506
197 + 31594309 = 31594506
233 + 31594273 = 31594506

Showing the first eight; more decompositions exist.
