Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681826, here are decompositions:

5 + 8681821 = 8681826
37 + 8681789 = 8681826
47 + 8681779 = 8681826
89 + 8681737 = 8681826
157 + 8681669 = 8681826
163 + 8681663 = 8681826
239 + 8681587 = 8681826
277 + 8681549 = 8681826

Showing the first eight; more decompositions exist.
