Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598828, here are decompositions:

127 + 31598701 = 31598828
181 + 31598647 = 31598828
307 + 31598521 = 31598828
379 + 31598449 = 31598828
409 + 31598419 = 31598828
601 + 31598227 = 31598828
691 + 31598137 = 31598828
727 + 31598101 = 31598828

Showing the first eight; more decompositions exist.
