Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655866, here are decompositions:

7 + 8655859 = 8655866
97 + 8655769 = 8655866
127 + 8655739 = 8655866
229 + 8655637 = 8655866
409 + 8655457 = 8655866
433 + 8655433 = 8655866
463 + 8655403 = 8655866
523 + 8655343 = 8655866

Showing the first eight; more decompositions exist.
