Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598000, here are decompositions:

3 + 31597997 = 31598000
13 + 31597987 = 31598000
67 + 31597933 = 31598000
73 + 31597927 = 31598000
127 + 31597873 = 31598000
157 + 31597843 = 31598000
199 + 31597801 = 31598000
223 + 31597777 = 31598000

Showing the first eight; more decompositions exist.
