Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594452, here are decompositions:

23 + 31594429 = 31594452
31 + 31594421 = 31594452
53 + 31594399 = 31594452
59 + 31594393 = 31594452
79 + 31594373 = 31594452
101 + 31594351 = 31594452
179 + 31594273 = 31594452
181 + 31594271 = 31594452

Showing the first eight; more decompositions exist.
