Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655686, here are decompositions:

7 + 8655679 = 8655686
37 + 8655649 = 8655686
229 + 8655457 = 8655686
283 + 8655403 = 8655686
337 + 8655349 = 8655686
373 + 8655313 = 8655686
379 + 8655307 = 8655686
727 + 8654959 = 8655686

Showing the first eight; more decompositions exist.
