Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671146, here are decompositions:

13 + 8671133 = 8671146
19 + 8671127 = 8671146
47 + 8671099 = 8671146
79 + 8671067 = 8671146
83 + 8671063 = 8671146
89 + 8671057 = 8671146
137 + 8671009 = 8671146
139 + 8671007 = 8671146

Showing the first eight; more decompositions exist.
