Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598904, here are decompositions:

17 + 31598887 = 31598904
31 + 31598873 = 31598904
37 + 31598867 = 31598904
41 + 31598863 = 31598904
47 + 31598857 = 31598904
151 + 31598753 = 31598904
257 + 31598647 = 31598904
313 + 31598591 = 31598904

Showing the first eight; more decompositions exist.
