Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599164, here are decompositions:

7 + 31599157 = 31599164
61 + 31599103 = 31599164
211 + 31598953 = 31599164
241 + 31598923 = 31599164
277 + 31598887 = 31599164
307 + 31598857 = 31599164
463 + 31598701 = 31599164
643 + 31598521 = 31599164

Showing the first eight; more decompositions exist.
