Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598806, here are decompositions:

17 + 31598789 = 31598806
23 + 31598783 = 31598806
53 + 31598753 = 31598806
89 + 31598717 = 31598806
137 + 31598669 = 31598806
263 + 31598543 = 31598806
269 + 31598537 = 31598806
293 + 31598513 = 31598806

Showing the first eight; more decompositions exist.
