Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597944, here are decompositions:

11 + 31597933 = 31597944
17 + 31597927 = 31597944
31 + 31597913 = 31597944
67 + 31597877 = 31597944
71 + 31597873 = 31597944
101 + 31597843 = 31597944
151 + 31597793 = 31597944
167 + 31597777 = 31597944

Showing the first eight; more decompositions exist.
