Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598944, here are decompositions:

5 + 31598939 = 31598944
11 + 31598933 = 31598944
17 + 31598927 = 31598944
71 + 31598873 = 31598944
173 + 31598771 = 31598944
191 + 31598753 = 31598944
227 + 31598717 = 31598944
257 + 31598687 = 31598944

Showing the first eight; more decompositions exist.
