Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642924, here are decompositions:

13 + 8642911 = 8642924
61 + 8642863 = 8642924
67 + 8642857 = 8642924
151 + 8642773 = 8642924
163 + 8642761 = 8642924
457 + 8642467 = 8642924
541 + 8642383 = 8642924
643 + 8642281 = 8642924

Showing the first eight; more decompositions exist.
