Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594392, here are decompositions:

19 + 31594373 = 31594392
41 + 31594351 = 31594392
59 + 31594333 = 31594392
61 + 31594331 = 31594392
83 + 31594309 = 31594392
199 + 31594193 = 31594392
229 + 31594163 = 31594392
233 + 31594159 = 31594392

Showing the first eight; more decompositions exist.
