Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655470, here are decompositions:

13 + 8655457 = 8655470
37 + 8655433 = 8655470
67 + 8655403 = 8655470
127 + 8655343 = 8655470
139 + 8655331 = 8655470
157 + 8655313 = 8655470
163 + 8655307 = 8655470
211 + 8655259 = 8655470

Showing the first eight; more decompositions exist.
