Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655566, here are decompositions:

109 + 8655457 = 8655566
163 + 8655403 = 8655566
223 + 8655343 = 8655566
307 + 8655259 = 8655566
349 + 8655217 = 8655566
463 + 8655103 = 8655566
607 + 8654959 = 8655566
727 + 8654839 = 8655566

Showing the first eight; more decompositions exist.
