Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649418, here are decompositions:

47 + 8649371 = 8649418
101 + 8649317 = 8649418
179 + 8649239 = 8649418
191 + 8649227 = 8649418
227 + 8649191 = 8649418
347 + 8649071 = 8649418
389 + 8649029 = 8649418
587 + 8648831 = 8649418

Showing the first eight; more decompositions exist.
