Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646662, here are decompositions:

103 + 8646559 = 8646662
151 + 8646511 = 8646662
439 + 8646223 = 8646662
499 + 8646163 = 8646662
601 + 8646061 = 8646662
691 + 8645971 = 8646662
859 + 8645803 = 8646662
1009 + 8645653 = 8646662

Showing the first eight; more decompositions exist.
