Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681036, here are decompositions:

43 + 8680993 = 8681036
97 + 8680939 = 8681036
127 + 8680909 = 8681036
223 + 8680813 = 8681036
283 + 8680753 = 8681036
313 + 8680723 = 8681036
337 + 8680699 = 8681036
367 + 8680669 = 8681036

Showing the first eight; more decompositions exist.
