Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681072, here are decompositions:

13 + 8681059 = 8681072
79 + 8680993 = 8681072
151 + 8680921 = 8681072
163 + 8680909 = 8681072
271 + 8680801 = 8681072
331 + 8680741 = 8681072
349 + 8680723 = 8681072
373 + 8680699 = 8681072

Showing the first eight; more decompositions exist.
