Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594832, here are decompositions:

19 + 31594813 = 31594832
103 + 31594729 = 31594832
151 + 31594681 = 31594832
223 + 31594609 = 31594832
331 + 31594501 = 31594832
433 + 31594399 = 31594832
439 + 31594393 = 31594832
499 + 31594333 = 31594832

Showing the first eight; more decompositions exist.
