Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598266, here are decompositions:

5 + 31598261 = 31598266
53 + 31598213 = 31598266
233 + 31598033 = 31598266
239 + 31598027 = 31598266
257 + 31598009 = 31598266
269 + 31597997 = 31598266
353 + 31597913 = 31598266
389 + 31597877 = 31598266

Showing the first eight; more decompositions exist.
