Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671662, here are decompositions:

23 + 8671639 = 8671662
29 + 8671633 = 8671662
31 + 8671631 = 8671662
73 + 8671589 = 8671662
79 + 8671583 = 8671662
89 + 8671573 = 8671662
113 + 8671549 = 8671662
151 + 8671511 = 8671662

Showing the first eight; more decompositions exist.
