Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756556, here are decompositions:

5 + 8756551 = 8756556
23 + 8756533 = 8756556
37 + 8756519 = 8756556
47 + 8756509 = 8756556
97 + 8756459 = 8756556
163 + 8756393 = 8756556
199 + 8756357 = 8756556
223 + 8756333 = 8756556

Showing the first eight; more decompositions exist.
