Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655486, here are decompositions:

29 + 8655457 = 8655486
53 + 8655433 = 8655486
83 + 8655403 = 8655486
137 + 8655349 = 8655486
173 + 8655313 = 8655486
179 + 8655307 = 8655486
199 + 8655287 = 8655486
223 + 8655263 = 8655486

Showing the first eight; more decompositions exist.
