Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671672, here are decompositions:

3 + 8671669 = 8671672
41 + 8671631 = 8671672
83 + 8671589 = 8671672
89 + 8671583 = 8671672
173 + 8671499 = 8671672
263 + 8671409 = 8671672
311 + 8671361 = 8671672
479 + 8671193 = 8671672

Showing the first eight; more decompositions exist.
