Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620522, here are decompositions:

23 + 8620499 = 8620522
173 + 8620349 = 8620522
233 + 8620289 = 8620522
263 + 8620259 = 8620522
311 + 8620211 = 8620522
389 + 8620133 = 8620522
401 + 8620121 = 8620522
479 + 8620043 = 8620522

Showing the first eight; more decompositions exist.
