Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687430, here are decompositions:

7 + 8687423 = 8687430
29 + 8687401 = 8687430
43 + 8687387 = 8687430
47 + 8687383 = 8687430
61 + 8687369 = 8687430
67 + 8687363 = 8687430
71 + 8687359 = 8687430
109 + 8687321 = 8687430

Showing the first eight; more decompositions exist.
