Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681004, here are decompositions:

11 + 8680993 = 8681004
53 + 8680951 = 8681004
83 + 8680921 = 8681004
97 + 8680907 = 8681004
103 + 8680901 = 8681004
181 + 8680823 = 8681004
191 + 8680813 = 8681004
193 + 8680811 = 8681004

Showing the first eight; more decompositions exist.
