Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681262, here are decompositions:

11 + 8681251 = 8681262
19 + 8681243 = 8681262
41 + 8681221 = 8681262
71 + 8681191 = 8681262
103 + 8681159 = 8681262
131 + 8681131 = 8681262
151 + 8681111 = 8681262
173 + 8681089 = 8681262

Showing the first eight; more decompositions exist.
