Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681506, here are decompositions:

3 + 8681503 = 8681506
17 + 8681489 = 8681506
23 + 8681483 = 8681506
59 + 8681447 = 8681506
137 + 8681369 = 8681506
149 + 8681357 = 8681506
263 + 8681243 = 8681506
293 + 8681213 = 8681506

Showing the first eight; more decompositions exist.
