Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681244, here are decompositions:

23 + 8681221 = 8681244
31 + 8681213 = 8681244
37 + 8681207 = 8681244
53 + 8681191 = 8681244
67 + 8681177 = 8681244
113 + 8681131 = 8681244
127 + 8681117 = 8681244
167 + 8681077 = 8681244

Showing the first eight; more decompositions exist.
