Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643782, here are decompositions:

3 + 8643779 = 8643782
61 + 8643721 = 8643782
109 + 8643673 = 8643782
151 + 8643631 = 8643782
163 + 8643619 = 8643782
193 + 8643589 = 8643782
349 + 8643433 = 8643782
373 + 8643409 = 8643782

Showing the first eight; more decompositions exist.
