Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649370, here are decompositions:

3 + 8649367 = 8649370
17 + 8649353 = 8649370
47 + 8649323 = 8649370
53 + 8649317 = 8649370
71 + 8649299 = 8649370
131 + 8649239 = 8649370
173 + 8649197 = 8649370
179 + 8649191 = 8649370

Showing the first eight; more decompositions exist.
