Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659220, here are decompositions:

13 + 8659207 = 8659220
67 + 8659153 = 8659220
211 + 8659009 = 8659220
223 + 8658997 = 8659220
277 + 8658943 = 8659220
373 + 8658847 = 8659220
463 + 8658757 = 8659220
523 + 8658697 = 8659220

Showing the first eight; more decompositions exist.
