Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681012, here are decompositions:

3 + 8681009 = 8681012
19 + 8680993 = 8681012
61 + 8680951 = 8681012
73 + 8680939 = 8681012
103 + 8680909 = 8681012
199 + 8680813 = 8681012
211 + 8680801 = 8681012
271 + 8680741 = 8681012

Showing the first eight; more decompositions exist.
