Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655320, here are decompositions:

7 + 8655313 = 8655320
13 + 8655307 = 8655320
61 + 8655259 = 8655320
103 + 8655217 = 8655320
109 + 8655211 = 8655320
283 + 8655037 = 8655320
313 + 8655007 = 8655320
379 + 8654941 = 8655320

Showing the first eight; more decompositions exist.
