Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598984, here are decompositions:

31 + 31598953 = 31598984
37 + 31598947 = 31598984
61 + 31598923 = 31598984
73 + 31598911 = 31598984
97 + 31598887 = 31598984
127 + 31598857 = 31598984
283 + 31598701 = 31598984
337 + 31598647 = 31598984

Showing the first eight; more decompositions exist.
