Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594118, here are decompositions:

37 + 31594081 = 31594118
79 + 31594039 = 31594118
181 + 31593937 = 31594118
331 + 31593787 = 31594118
397 + 31593721 = 31594118
487 + 31593631 = 31594118
547 + 31593571 = 31594118
601 + 31593517 = 31594118

Showing the first eight; more decompositions exist.
