Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594670, here are decompositions:

43 + 31594627 = 31594670
61 + 31594609 = 31594670
73 + 31594597 = 31594670
97 + 31594573 = 31594670
181 + 31594489 = 31594670
241 + 31594429 = 31594670
271 + 31594399 = 31594670
277 + 31594393 = 31594670

Showing the first eight; more decompositions exist.
