Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687422, here are decompositions:

41 + 8687381 = 8687422
53 + 8687369 = 8687422
59 + 8687363 = 8687422
101 + 8687321 = 8687422
113 + 8687309 = 8687422
131 + 8687291 = 8687422
173 + 8687249 = 8687422
239 + 8687183 = 8687422

Showing the first eight; more decompositions exist.
