Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616648, here are decompositions:

101 + 8616547 = 8616648
107 + 8616541 = 8616648
149 + 8616499 = 8616648
191 + 8616457 = 8616648
241 + 8616407 = 8616648
251 + 8616397 = 8616648
269 + 8616379 = 8616648
277 + 8616371 = 8616648

Showing the first eight; more decompositions exist.
