Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621466, here are decompositions:

13 + 8621453 = 8621466
23 + 8621443 = 8621466
37 + 8621429 = 8621466
53 + 8621413 = 8621466
89 + 8621377 = 8621466
127 + 8621339 = 8621466
157 + 8621309 = 8621466
167 + 8621299 = 8621466

Showing the first eight; more decompositions exist.
