Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598636, here are decompositions:

283 + 31598353 = 31598636
337 + 31598299 = 31598636
397 + 31598239 = 31598636
409 + 31598227 = 31598636
457 + 31598179 = 31598636
499 + 31598137 = 31598636
607 + 31598029 = 31598636
709 + 31597927 = 31598636

Showing the first eight; more decompositions exist.
