Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618466, here are decompositions:

23 + 8618443 = 8618466
37 + 8618429 = 8618466
53 + 8618413 = 8618466
79 + 8618387 = 8618466
89 + 8618377 = 8618466
127 + 8618339 = 8618466
137 + 8618329 = 8618466
139 + 8618327 = 8618466

Showing the first eight; more decompositions exist.
