Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655488, here are decompositions:

31 + 8655457 = 8655488
67 + 8655421 = 8655488
139 + 8655349 = 8655488
157 + 8655331 = 8655488
181 + 8655307 = 8655488
229 + 8655259 = 8655488
271 + 8655217 = 8655488
277 + 8655211 = 8655488

Showing the first eight; more decompositions exist.
