Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681226, here are decompositions:

5 + 8681221 = 8681226
13 + 8681213 = 8681226
19 + 8681207 = 8681226
67 + 8681159 = 8681226
97 + 8681129 = 8681226
109 + 8681117 = 8681226
137 + 8681089 = 8681226
149 + 8681077 = 8681226

Showing the first eight; more decompositions exist.
