Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687494, here are decompositions:

17 + 8687477 = 8687494
41 + 8687453 = 8687494
71 + 8687423 = 8687494
107 + 8687387 = 8687494
113 + 8687381 = 8687494
131 + 8687363 = 8687494
173 + 8687321 = 8687494
191 + 8687303 = 8687494

Showing the first eight; more decompositions exist.
