Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655216, here are decompositions:

5 + 8655211 = 8655216
19 + 8655197 = 8655216
43 + 8655173 = 8655216
67 + 8655149 = 8655216
113 + 8655103 = 8655216
179 + 8655037 = 8655216
257 + 8654959 = 8655216
379 + 8654837 = 8655216

Showing the first eight; more decompositions exist.
