Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594168, here are decompositions:

5 + 31594163 = 31594168
17 + 31594151 = 31594168
71 + 31594097 = 31594168
107 + 31594061 = 31594168
401 + 31593767 = 31594168
449 + 31593719 = 31594168
479 + 31593689 = 31594168
521 + 31593647 = 31594168

Showing the first eight; more decompositions exist.
