Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687370, here are decompositions:

7 + 8687363 = 8687370
11 + 8687359 = 8687370
53 + 8687317 = 8687370
61 + 8687309 = 8687370
67 + 8687303 = 8687370
71 + 8687299 = 8687370
79 + 8687291 = 8687370
137 + 8687233 = 8687370

Showing the first eight; more decompositions exist.
