Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594630, here are decompositions:

3 + 31594627 = 31594630
17 + 31594613 = 31594630
47 + 31594583 = 31594630
83 + 31594547 = 31594630
167 + 31594463 = 31594630
257 + 31594373 = 31594630
359 + 31594271 = 31594630
383 + 31594247 = 31594630

Showing the first eight; more decompositions exist.
