Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8607040, here are decompositions:

11 + 8607029 = 8607040
17 + 8607023 = 8607040
41 + 8606999 = 8607040
83 + 8606957 = 8607040
131 + 8606909 = 8607040
251 + 8606789 = 8607040
311 + 8606729 = 8607040
347 + 8606693 = 8607040

Showing the first eight; more decompositions exist.
