Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649784, here are decompositions:

23 + 8649761 = 8649784
107 + 8649677 = 8649784
113 + 8649671 = 8649784
173 + 8649611 = 8649784
251 + 8649533 = 8649784
263 + 8649521 = 8649784
293 + 8649491 = 8649784
317 + 8649467 = 8649784

Showing the first eight; more decompositions exist.
