Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649724, here are decompositions:

3 + 8649721 = 8649724
47 + 8649677 = 8649724
53 + 8649671 = 8649724
101 + 8649623 = 8649724
113 + 8649611 = 8649724
191 + 8649533 = 8649724
233 + 8649491 = 8649724
257 + 8649467 = 8649724

Showing the first eight; more decompositions exist.
