Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700340, here are decompositions:

41 + 8700299 = 8700340
53 + 8700287 = 8700340
59 + 8700281 = 8700340
83 + 8700257 = 8700340
101 + 8700239 = 8700340
179 + 8700161 = 8700340
227 + 8700113 = 8700340
269 + 8700071 = 8700340

Showing the first eight; more decompositions exist.
