Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655584, here are decompositions:

127 + 8655457 = 8655584
151 + 8655433 = 8655584
163 + 8655421 = 8655584
181 + 8655403 = 8655584
241 + 8655343 = 8655584
271 + 8655313 = 8655584
277 + 8655307 = 8655584
367 + 8655217 = 8655584

Showing the first eight; more decompositions exist.
