Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12998, here are decompositions:

19 + 12979 = 12998
31 + 12967 = 12998
79 + 12919 = 12998
109 + 12889 = 12998
157 + 12841 = 12998
199 + 12799 = 12998
241 + 12757 = 12998
277 + 12721 = 12998

Showing the first eight; more decompositions exist.
