Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594412, here are decompositions:

13 + 31594399 = 31594412
19 + 31594393 = 31594412
61 + 31594351 = 31594412
79 + 31594333 = 31594412
103 + 31594309 = 31594412
139 + 31594273 = 31594412
331 + 31594081 = 31594412
349 + 31594063 = 31594412

Showing the first eight; more decompositions exist.
