Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622520, here are decompositions:

29 + 8622491 = 8622520
47 + 8622473 = 8622520
59 + 8622461 = 8622520
107 + 8622413 = 8622520
167 + 8622353 = 8622520
197 + 8622323 = 8622520
227 + 8622293 = 8622520
233 + 8622287 = 8622520

Showing the first eight; more decompositions exist.
