Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671338, here are decompositions:

7 + 8671331 = 8671338
17 + 8671321 = 8671338
31 + 8671307 = 8671338
47 + 8671291 = 8671338
89 + 8671249 = 8671338
107 + 8671231 = 8671338
191 + 8671147 = 8671338
211 + 8671127 = 8671338

Showing the first eight; more decompositions exist.
