Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671208, here are decompositions:

31 + 8671177 = 8671208
61 + 8671147 = 8671208
109 + 8671099 = 8671208
151 + 8671057 = 8671208
157 + 8671051 = 8671208
199 + 8671009 = 8671208
211 + 8670997 = 8671208
397 + 8670811 = 8671208

Showing the first eight; more decompositions exist.
