Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681228, here are decompositions:

7 + 8681221 = 8681228
37 + 8681191 = 8681228
97 + 8681131 = 8681228
139 + 8681089 = 8681228
151 + 8681077 = 8681228
181 + 8681047 = 8681228
277 + 8680951 = 8681228
307 + 8680921 = 8681228

Showing the first eight; more decompositions exist.
