Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672028, here are decompositions:

37 + 8671991 = 8672028
41 + 8671987 = 8672028
47 + 8671981 = 8672028
61 + 8671967 = 8672028
109 + 8671919 = 8672028
191 + 8671837 = 8672028
307 + 8671721 = 8672028
317 + 8671711 = 8672028

Showing the first eight; more decompositions exist.
