Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594466, here are decompositions:

3 + 31594463 = 31594466
37 + 31594429 = 31594466
67 + 31594399 = 31594466
73 + 31594393 = 31594466
157 + 31594309 = 31594466
193 + 31594273 = 31594466
229 + 31594237 = 31594466
307 + 31594159 = 31594466

Showing the first eight; more decompositions exist.
