Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594458, here are decompositions:

29 + 31594429 = 31594458
37 + 31594421 = 31594458
59 + 31594399 = 31594458
107 + 31594351 = 31594458
127 + 31594331 = 31594458
149 + 31594309 = 31594458
211 + 31594247 = 31594458
307 + 31594151 = 31594458

Showing the first eight; more decompositions exist.
