Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647550, here are decompositions:

13 + 8647537 = 8647550
19 + 8647531 = 8647550
103 + 8647447 = 8647550
139 + 8647411 = 8647550
157 + 8647393 = 8647550
181 + 8647369 = 8647550
277 + 8647273 = 8647550
367 + 8647183 = 8647550

Showing the first eight; more decompositions exist.
