Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671130, here are decompositions:

3 + 8671127 = 8671130
31 + 8671099 = 8671130
67 + 8671063 = 8671130
73 + 8671057 = 8671130
79 + 8671051 = 8671130
211 + 8670919 = 8671130
379 + 8670751 = 8671130
421 + 8670709 = 8671130

Showing the first eight; more decompositions exist.
