Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8607828, here are decompositions:

7 + 8607821 = 8607828
59 + 8607769 = 8607828
79 + 8607749 = 8607828
139 + 8607689 = 8607828
191 + 8607637 = 8607828
197 + 8607631 = 8607828
199 + 8607629 = 8607828
227 + 8607601 = 8607828

Showing the first eight; more decompositions exist.
