Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594430, here are decompositions:

31 + 31594399 = 31594430
37 + 31594393 = 31594430
79 + 31594351 = 31594430
97 + 31594333 = 31594430
157 + 31594273 = 31594430
193 + 31594237 = 31594430
271 + 31594159 = 31594430
349 + 31594081 = 31594430

Showing the first eight; more decompositions exist.
