Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622478, here are decompositions:

5 + 8622473 = 8622478
17 + 8622461 = 8622478
191 + 8622287 = 8622478
269 + 8622209 = 8622478
461 + 8622017 = 8622478
467 + 8622011 = 8622478
617 + 8621861 = 8622478
647 + 8621831 = 8622478

Showing the first eight; more decompositions exist.
