Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687426, here are decompositions:

3 + 8687423 = 8687426
43 + 8687383 = 8687426
67 + 8687359 = 8687426
109 + 8687317 = 8687426
127 + 8687299 = 8687426
193 + 8687233 = 8687426
199 + 8687227 = 8687426
229 + 8687197 = 8687426

Showing the first eight; more decompositions exist.
