Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655582, here are decompositions:

149 + 8655433 = 8655582
179 + 8655403 = 8655582
181 + 8655401 = 8655582
211 + 8655371 = 8655582
233 + 8655349 = 8655582
239 + 8655343 = 8655582
251 + 8655331 = 8655582
269 + 8655313 = 8655582

Showing the first eight; more decompositions exist.
