Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598366, here are decompositions:

3 + 31598363 = 31598366
13 + 31598353 = 31598366
67 + 31598299 = 31598366
127 + 31598239 = 31598366
139 + 31598227 = 31598366
223 + 31598143 = 31598366
229 + 31598137 = 31598366
337 + 31598029 = 31598366

Showing the first eight; more decompositions exist.
