Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594356, here are decompositions:

5 + 31594351 = 31594356
23 + 31594333 = 31594356
47 + 31594309 = 31594356
83 + 31594273 = 31594356
109 + 31594247 = 31594356
163 + 31594193 = 31594356
193 + 31594163 = 31594356
197 + 31594159 = 31594356

Showing the first eight; more decompositions exist.
