Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598486, here are decompositions:

37 + 31598449 = 31598486
67 + 31598419 = 31598486
109 + 31598377 = 31598486
307 + 31598179 = 31598486
349 + 31598137 = 31598486
457 + 31598029 = 31598486
499 + 31597987 = 31598486
607 + 31597879 = 31598486

Showing the first eight; more decompositions exist.
