Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681268, here are decompositions:

5 + 8681263 = 8681268
17 + 8681251 = 8681268
47 + 8681221 = 8681268
61 + 8681207 = 8681268
109 + 8681159 = 8681268
137 + 8681131 = 8681268
139 + 8681129 = 8681268
151 + 8681117 = 8681268

Showing the first eight; more decompositions exist.
