Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649538, here are decompositions:

5 + 8649533 = 8649538
17 + 8649521 = 8649538
47 + 8649491 = 8649538
59 + 8649479 = 8649538
71 + 8649467 = 8649538
167 + 8649371 = 8649538
239 + 8649299 = 8649538
311 + 8649227 = 8649538

Showing the first eight; more decompositions exist.
