Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620556, here are decompositions:

3 + 8620553 = 8620556
13 + 8620543 = 8620556
127 + 8620429 = 8620556
163 + 8620393 = 8620556
229 + 8620327 = 8620556
337 + 8620219 = 8620556
367 + 8620189 = 8620556
397 + 8620159 = 8620556

Showing the first eight; more decompositions exist.
