Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687380, here are decompositions:

11 + 8687369 = 8687380
17 + 8687363 = 8687380
59 + 8687321 = 8687380
71 + 8687309 = 8687380
89 + 8687291 = 8687380
131 + 8687249 = 8687380
167 + 8687213 = 8687380
173 + 8687207 = 8687380

Showing the first eight; more decompositions exist.
