Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8607808, here are decompositions:

5 + 8607803 = 8607808
59 + 8607749 = 8607808
71 + 8607737 = 8607808
149 + 8607659 = 8607808
179 + 8607629 = 8607808
269 + 8607539 = 8607808
359 + 8607449 = 8607808
401 + 8607407 = 8607808

Showing the first eight; more decompositions exist.
