Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649748, here are decompositions:

59 + 8649689 = 8649748
71 + 8649677 = 8649748
137 + 8649611 = 8649748
167 + 8649581 = 8649748
227 + 8649521 = 8649748
257 + 8649491 = 8649748
269 + 8649479 = 8649748
281 + 8649467 = 8649748

Showing the first eight; more decompositions exist.
