Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619662, here are decompositions:

13 + 8619649 = 8619662
61 + 8619601 = 8619662
151 + 8619511 = 8619662
193 + 8619469 = 8619662
223 + 8619439 = 8619662
229 + 8619433 = 8619662
241 + 8619421 = 8619662
421 + 8619241 = 8619662

Showing the first eight; more decompositions exist.
