Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594422, here are decompositions:

23 + 31594399 = 31594422
29 + 31594393 = 31594422
71 + 31594351 = 31594422
89 + 31594333 = 31594422
113 + 31594309 = 31594422
149 + 31594273 = 31594422
151 + 31594271 = 31594422
229 + 31594193 = 31594422

Showing the first eight; more decompositions exist.
