Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599384, here are decompositions:

31 + 31599353 = 31599384
43 + 31599341 = 31599384
71 + 31599313 = 31599384
137 + 31599247 = 31599384
191 + 31599193 = 31599384
211 + 31599173 = 31599384
227 + 31599157 = 31599384
281 + 31599103 = 31599384

Showing the first eight; more decompositions exist.
