Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681290, here are decompositions:

3 + 8681287 = 8681290
47 + 8681243 = 8681290
83 + 8681207 = 8681290
113 + 8681177 = 8681290
131 + 8681159 = 8681290
173 + 8681117 = 8681290
179 + 8681111 = 8681290
269 + 8681021 = 8681290

Showing the first eight; more decompositions exist.
