Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656556, here are decompositions:

19 + 8656537 = 8656556
79 + 8656477 = 8656556
157 + 8656399 = 8656556
163 + 8656393 = 8656556
193 + 8656363 = 8656556
199 + 8656357 = 8656556
277 + 8656279 = 8656556
283 + 8656273 = 8656556

Showing the first eight; more decompositions exist.
