Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649478, here are decompositions:

11 + 8649467 = 8649478
59 + 8649419 = 8649478
107 + 8649371 = 8649478
179 + 8649299 = 8649478
239 + 8649239 = 8649478
251 + 8649227 = 8649478
281 + 8649197 = 8649478
449 + 8649029 = 8649478

Showing the first eight; more decompositions exist.
