Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594440, here are decompositions:

11 + 31594429 = 31594440
19 + 31594421 = 31594440
41 + 31594399 = 31594440
47 + 31594393 = 31594440
67 + 31594373 = 31594440
89 + 31594351 = 31594440
107 + 31594333 = 31594440
109 + 31594331 = 31594440

Showing the first eight; more decompositions exist.
