Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643962, here are decompositions:

3 + 8643959 = 8643962
43 + 8643919 = 8643962
73 + 8643889 = 8643962
241 + 8643721 = 8643962
331 + 8643631 = 8643962
373 + 8643589 = 8643962
619 + 8643343 = 8643962
739 + 8643223 = 8643962

Showing the first eight; more decompositions exist.
