Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681078, here are decompositions:

19 + 8681059 = 8681078
31 + 8681047 = 8681078
127 + 8680951 = 8681078
139 + 8680939 = 8681078
157 + 8680921 = 8681078
277 + 8680801 = 8681078
337 + 8680741 = 8681078
379 + 8680699 = 8681078

Showing the first eight; more decompositions exist.
