Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687652, here are decompositions:

11 + 8687641 = 8687652
53 + 8687599 = 8687652
131 + 8687521 = 8687652
139 + 8687513 = 8687652
173 + 8687479 = 8687652
191 + 8687461 = 8687652
199 + 8687453 = 8687652
223 + 8687429 = 8687652

Showing the first eight; more decompositions exist.
