Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687694, here are decompositions:

7 + 8687687 = 8687694
23 + 8687671 = 8687694
53 + 8687641 = 8687694
107 + 8687587 = 8687694
173 + 8687521 = 8687694
181 + 8687513 = 8687694
227 + 8687467 = 8687694
233 + 8687461 = 8687694

Showing the first eight; more decompositions exist.
