Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8607920, here are decompositions:

3 + 8607917 = 8607920
7 + 8607913 = 8607920
19 + 8607901 = 8607920
37 + 8607883 = 8607920
151 + 8607769 = 8607920
283 + 8607637 = 8607920
337 + 8607583 = 8607920
439 + 8607481 = 8607920

Showing the first eight; more decompositions exist.
