Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649550, here are decompositions:

17 + 8649533 = 8649550
29 + 8649521 = 8649550
59 + 8649491 = 8649550
71 + 8649479 = 8649550
83 + 8649467 = 8649550
131 + 8649419 = 8649550
167 + 8649383 = 8649550
179 + 8649371 = 8649550

Showing the first eight; more decompositions exist.
