Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687388, here are decompositions:

5 + 8687383 = 8687388
7 + 8687381 = 8687388
19 + 8687369 = 8687388
29 + 8687359 = 8687388
67 + 8687321 = 8687388
71 + 8687317 = 8687388
79 + 8687309 = 8687388
89 + 8687299 = 8687388

Showing the first eight; more decompositions exist.
