Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597898, here are decompositions:

19 + 31597879 = 31597898
97 + 31597801 = 31597898
181 + 31597717 = 31597898
349 + 31597549 = 31597898
487 + 31597411 = 31597898
769 + 31597129 = 31597898
907 + 31596991 = 31597898
991 + 31596907 = 31597898

Showing the first eight; more decompositions exist.
