Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681070, here are decompositions:

11 + 8681059 = 8681070
23 + 8681047 = 8681070
61 + 8681009 = 8681070
67 + 8681003 = 8681070
131 + 8680939 = 8681070
149 + 8680921 = 8681070
163 + 8680907 = 8681070
199 + 8680871 = 8681070

Showing the first eight; more decompositions exist.
