Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671980, here are decompositions:

13 + 8671967 = 8671980
43 + 8671937 = 8671980
61 + 8671919 = 8671980
73 + 8671907 = 8671980
211 + 8671769 = 8671980
241 + 8671739 = 8671980
269 + 8671711 = 8671980
271 + 8671709 = 8671980

Showing the first eight; more decompositions exist.
