Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8607878, here are decompositions:

7 + 8607871 = 8607878
109 + 8607769 = 8607878
211 + 8607667 = 8607878
241 + 8607637 = 8607878
277 + 8607601 = 8607878
397 + 8607481 = 8607878
571 + 8607307 = 8607878
607 + 8607271 = 8607878

Showing the first eight; more decompositions exist.
