Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622732, here are decompositions:

11 + 8622721 = 8622732
211 + 8622521 = 8622732
233 + 8622499 = 8622732
241 + 8622491 = 8622732
263 + 8622469 = 8622732
269 + 8622463 = 8622732
271 + 8622461 = 8622732
311 + 8622421 = 8622732

Showing the first eight; more decompositions exist.
