Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598216, here are decompositions:

3 + 31598213 = 31598216
37 + 31598179 = 31598216
73 + 31598143 = 31598216
79 + 31598137 = 31598216
229 + 31597987 = 31598216
283 + 31597933 = 31598216
337 + 31597879 = 31598216
373 + 31597843 = 31598216

Showing the first eight; more decompositions exist.
