Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594512, here are decompositions:

11 + 31594501 = 31594512
23 + 31594489 = 31594512
83 + 31594429 = 31594512
113 + 31594399 = 31594512
139 + 31594373 = 31594512
179 + 31594333 = 31594512
181 + 31594331 = 31594512
239 + 31594273 = 31594512

Showing the first eight; more decompositions exist.
