Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687378, here are decompositions:

19 + 8687359 = 8687378
61 + 8687317 = 8687378
79 + 8687299 = 8687378
151 + 8687227 = 8687378
181 + 8687197 = 8687378
229 + 8687149 = 8687378
379 + 8686999 = 8687378
397 + 8686981 = 8687378

Showing the first eight; more decompositions exist.
