Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709826, here are decompositions:

5 + 8709821 = 8709826
89 + 8709737 = 8709826
107 + 8709719 = 8709826
113 + 8709713 = 8709826
149 + 8709677 = 8709826
173 + 8709653 = 8709826
179 + 8709647 = 8709826
239 + 8709587 = 8709826

Showing the first eight; more decompositions exist.
