Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671818, here are decompositions:

7 + 8671811 = 8671818
79 + 8671739 = 8671818
97 + 8671721 = 8671818
107 + 8671711 = 8671818
109 + 8671709 = 8671818
149 + 8671669 = 8671818
179 + 8671639 = 8671818
229 + 8671589 = 8671818

Showing the first eight; more decompositions exist.
