Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618454, here are decompositions:

11 + 8618443 = 8618454
41 + 8618413 = 8618454
67 + 8618387 = 8618454
127 + 8618327 = 8618454
137 + 8618317 = 8618454
157 + 8618297 = 8618454
167 + 8618287 = 8618454
181 + 8618273 = 8618454

Showing the first eight; more decompositions exist.
