Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687850, here are decompositions:

23 + 8687827 = 8687850
53 + 8687797 = 8687850
79 + 8687771 = 8687850
137 + 8687713 = 8687850
151 + 8687699 = 8687850
163 + 8687687 = 8687850
179 + 8687671 = 8687850
181 + 8687669 = 8687850

Showing the first eight; more decompositions exist.
