Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671944, here are decompositions:

7 + 8671937 = 8671944
37 + 8671907 = 8671944
107 + 8671837 = 8671944
223 + 8671721 = 8671944
233 + 8671711 = 8671944
311 + 8671633 = 8671944
313 + 8671631 = 8671944
433 + 8671511 = 8671944

Showing the first eight; more decompositions exist.
