Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655270, here are decompositions:

7 + 8655263 = 8655270
11 + 8655259 = 8655270
53 + 8655217 = 8655270
59 + 8655211 = 8655270
73 + 8655197 = 8655270
97 + 8655173 = 8655270
103 + 8655167 = 8655270
167 + 8655103 = 8655270

Showing the first eight; more decompositions exist.
