Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681476, here are decompositions:

3 + 8681473 = 8681476
29 + 8681447 = 8681476
47 + 8681429 = 8681476
107 + 8681369 = 8681476
113 + 8681363 = 8681476
233 + 8681243 = 8681476
263 + 8681213 = 8681476
269 + 8681207 = 8681476

Showing the first eight; more decompositions exist.
