Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618556, here are decompositions:

73 + 8618483 = 8618556
113 + 8618443 = 8618556
127 + 8618429 = 8618556
179 + 8618377 = 8618556
227 + 8618329 = 8618556
229 + 8618327 = 8618556
239 + 8618317 = 8618556
263 + 8618293 = 8618556

Showing the first eight; more decompositions exist.
