Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672080, here are decompositions:

17 + 8672063 = 8672080
89 + 8671991 = 8672080
101 + 8671979 = 8672080
113 + 8671967 = 8672080
173 + 8671907 = 8672080
269 + 8671811 = 8672080
311 + 8671769 = 8672080
359 + 8671721 = 8672080

Showing the first eight; more decompositions exist.
