Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655530, here are decompositions:

3 + 8655527 = 8655530
73 + 8655457 = 8655530
97 + 8655433 = 8655530
109 + 8655421 = 8655530
127 + 8655403 = 8655530
181 + 8655349 = 8655530
199 + 8655331 = 8655530
223 + 8655307 = 8655530

Showing the first eight; more decompositions exist.
