Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599504, here are decompositions:

5 + 31599499 = 31599504
17 + 31599487 = 31599504
73 + 31599431 = 31599504
151 + 31599353 = 31599504
163 + 31599341 = 31599504
191 + 31599313 = 31599504
197 + 31599307 = 31599504
257 + 31599247 = 31599504

Showing the first eight; more decompositions exist.
