Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598084, here are decompositions:

73 + 31598011 = 31598084
97 + 31597987 = 31598084
151 + 31597933 = 31598084
157 + 31597927 = 31598084
211 + 31597873 = 31598084
241 + 31597843 = 31598084
283 + 31597801 = 31598084
307 + 31597777 = 31598084

Showing the first eight; more decompositions exist.
