Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655570, here are decompositions:

43 + 8655527 = 8655570
73 + 8655497 = 8655570
113 + 8655457 = 8655570
137 + 8655433 = 8655570
149 + 8655421 = 8655570
167 + 8655403 = 8655570
199 + 8655371 = 8655570
227 + 8655343 = 8655570

Showing the first eight; more decompositions exist.
