Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621462, here are decompositions:

19 + 8621443 = 8621462
163 + 8621299 = 8621462
181 + 8621281 = 8621462
373 + 8621089 = 8621462
379 + 8621083 = 8621462
601 + 8620861 = 8621462
739 + 8620723 = 8621462
823 + 8620639 = 8621462

Showing the first eight; more decompositions exist.
