Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8607728, here are decompositions:

61 + 8607667 = 8607728
97 + 8607631 = 8607728
127 + 8607601 = 8607728
331 + 8607397 = 8607728
421 + 8607307 = 8607728
457 + 8607271 = 8607728
487 + 8607241 = 8607728
769 + 8606959 = 8607728

Showing the first eight; more decompositions exist.
