Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681090, here are decompositions:

13 + 8681077 = 8681090
31 + 8681059 = 8681090
43 + 8681047 = 8681090
97 + 8680993 = 8681090
139 + 8680951 = 8681090
151 + 8680939 = 8681090
181 + 8680909 = 8681090
277 + 8680813 = 8681090

Showing the first eight; more decompositions exist.
