Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687170, here are decompositions:

29 + 8687141 = 8687170
53 + 8687117 = 8687170
83 + 8687087 = 8687170
101 + 8687069 = 8687170
269 + 8686901 = 8687170
281 + 8686889 = 8687170
293 + 8686877 = 8687170
449 + 8686721 = 8687170

Showing the first eight; more decompositions exist.
