Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681536, here are decompositions:

23 + 8681513 = 8681536
29 + 8681507 = 8681536
47 + 8681489 = 8681536
53 + 8681483 = 8681536
89 + 8681447 = 8681536
107 + 8681429 = 8681536
167 + 8681369 = 8681536
173 + 8681363 = 8681536

Showing the first eight; more decompositions exist.
