Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643662, here are decompositions:

31 + 8643631 = 8643662
43 + 8643619 = 8643662
73 + 8643589 = 8643662
229 + 8643433 = 8643662
439 + 8643223 = 8643662
463 + 8643199 = 8643662
541 + 8643121 = 8643662
571 + 8643091 = 8643662

Showing the first eight; more decompositions exist.
