Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594368, here are decompositions:

17 + 31594351 = 31594368
37 + 31594331 = 31594368
59 + 31594309 = 31594368
97 + 31594271 = 31594368
131 + 31594237 = 31594368
271 + 31594097 = 31594368
307 + 31594061 = 31594368
409 + 31593959 = 31594368

Showing the first eight; more decompositions exist.
