Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594700, here are decompositions:

19 + 31594681 = 31594700
73 + 31594627 = 31594700
103 + 31594597 = 31594700
127 + 31594573 = 31594700
199 + 31594501 = 31594700
211 + 31594489 = 31594700
271 + 31594429 = 31594700
307 + 31594393 = 31594700

Showing the first eight; more decompositions exist.
