Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687320, here are decompositions:

3 + 8687317 = 8687320
11 + 8687309 = 8687320
17 + 8687303 = 8687320
29 + 8687291 = 8687320
71 + 8687249 = 8687320
107 + 8687213 = 8687320
113 + 8687207 = 8687320
137 + 8687183 = 8687320

Showing the first eight; more decompositions exist.
