Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598064, here are decompositions:

7 + 31598057 = 31598064
31 + 31598033 = 31598064
37 + 31598027 = 31598064
53 + 31598011 = 31598064
67 + 31597997 = 31598064
103 + 31597961 = 31598064
131 + 31597933 = 31598064
137 + 31597927 = 31598064

Showing the first eight; more decompositions exist.
