Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655312, here are decompositions:

5 + 8655307 = 8655312
53 + 8655259 = 8655312
101 + 8655211 = 8655312
139 + 8655173 = 8655312
163 + 8655149 = 8655312
241 + 8655071 = 8655312
271 + 8655041 = 8655312
283 + 8655029 = 8655312

Showing the first eight; more decompositions exist.
