Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647556, here are decompositions:

19 + 8647537 = 8647556
97 + 8647459 = 8647556
109 + 8647447 = 8647556
139 + 8647417 = 8647556
163 + 8647393 = 8647556
283 + 8647273 = 8647556
373 + 8647183 = 8647556
433 + 8647123 = 8647556

Showing the first eight; more decompositions exist.
