Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639454, here are decompositions:

11 + 8639443 = 8639454
13 + 8639441 = 8639454
41 + 8639413 = 8639454
53 + 8639401 = 8639454
73 + 8639381 = 8639454
107 + 8639347 = 8639454
163 + 8639291 = 8639454
181 + 8639273 = 8639454

Showing the first eight; more decompositions exist.
