Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622672, here are decompositions:

61 + 8622611 = 8622672
109 + 8622563 = 8622672
151 + 8622521 = 8622672
173 + 8622499 = 8622672
181 + 8622491 = 8622672
199 + 8622473 = 8622672
211 + 8622461 = 8622672
251 + 8622421 = 8622672

Showing the first eight; more decompositions exist.
