Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594370, here are decompositions:

19 + 31594351 = 31594370
37 + 31594333 = 31594370
61 + 31594309 = 31594370
97 + 31594273 = 31594370
211 + 31594159 = 31594370
307 + 31594063 = 31594370
331 + 31594039 = 31594370
433 + 31593937 = 31594370

Showing the first eight; more decompositions exist.
