Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598306, here are decompositions:

7 + 31598299 = 31598306
67 + 31598239 = 31598306
79 + 31598227 = 31598306
127 + 31598179 = 31598306
163 + 31598143 = 31598306
277 + 31598029 = 31598306
373 + 31597933 = 31598306
379 + 31597927 = 31598306

Showing the first eight; more decompositions exist.
