Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649388, here are decompositions:

5 + 8649383 = 8649388
17 + 8649371 = 8649388
71 + 8649317 = 8649388
89 + 8649299 = 8649388
149 + 8649239 = 8649388
191 + 8649197 = 8649388
197 + 8649191 = 8649388
317 + 8649071 = 8649388

Showing the first eight; more decompositions exist.
