Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671812, here are decompositions:

43 + 8671769 = 8671812
73 + 8671739 = 8671812
101 + 8671711 = 8671812
103 + 8671709 = 8671812
173 + 8671639 = 8671812
179 + 8671633 = 8671812
181 + 8671631 = 8671812
223 + 8671589 = 8671812

Showing the first eight; more decompositions exist.
