Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594398, here are decompositions:

5 + 31594393 = 31594398
47 + 31594351 = 31594398
67 + 31594331 = 31594398
89 + 31594309 = 31594398
127 + 31594271 = 31594398
151 + 31594247 = 31594398
239 + 31594159 = 31594398
317 + 31594081 = 31594398

Showing the first eight; more decompositions exist.
