Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622556, here are decompositions:

83 + 8622473 = 8622556
197 + 8622359 = 8622556
233 + 8622323 = 8622556
263 + 8622293 = 8622556
269 + 8622287 = 8622556
347 + 8622209 = 8622556
419 + 8622137 = 8622556
443 + 8622113 = 8622556

Showing the first eight; more decompositions exist.
