Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661316, here are decompositions:

5 + 8661311 = 8661316
113 + 8661203 = 8661316
179 + 8661137 = 8661316
197 + 8661119 = 8661316
227 + 8661089 = 8661316
269 + 8661047 = 8661316
347 + 8660969 = 8661316
383 + 8660933 = 8661316

Showing the first eight; more decompositions exist.
