Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655456, here are decompositions:

23 + 8655433 = 8655456
53 + 8655403 = 8655456
107 + 8655349 = 8655456
113 + 8655343 = 8655456
149 + 8655307 = 8655456
193 + 8655263 = 8655456
197 + 8655259 = 8655456
239 + 8655217 = 8655456

Showing the first eight; more decompositions exist.
