Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649904, here are decompositions:

17 + 8649887 = 8649904
23 + 8649881 = 8649904
47 + 8649857 = 8649904
101 + 8649803 = 8649904
113 + 8649791 = 8649904
227 + 8649677 = 8649904
233 + 8649671 = 8649904
281 + 8649623 = 8649904

Showing the first eight; more decompositions exist.
