Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671782, here are decompositions:

13 + 8671769 = 8671782
43 + 8671739 = 8671782
61 + 8671721 = 8671782
71 + 8671711 = 8671782
73 + 8671709 = 8671782
113 + 8671669 = 8671782
149 + 8671633 = 8671782
151 + 8671631 = 8671782

Showing the first eight; more decompositions exist.
