Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687420, here are decompositions:

19 + 8687401 = 8687420
37 + 8687383 = 8687420
61 + 8687359 = 8687420
103 + 8687317 = 8687420
193 + 8687227 = 8687420
211 + 8687209 = 8687420
223 + 8687197 = 8687420
271 + 8687149 = 8687420

Showing the first eight; more decompositions exist.
