Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681376, here are decompositions:

7 + 8681369 = 8681376
13 + 8681363 = 8681376
17 + 8681359 = 8681376
19 + 8681357 = 8681376
59 + 8681317 = 8681376
89 + 8681287 = 8681376
113 + 8681263 = 8681376
163 + 8681213 = 8681376

Showing the first eight; more decompositions exist.
