Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649760, here are decompositions:

3 + 8649757 = 8649760
71 + 8649689 = 8649760
83 + 8649677 = 8649760
89 + 8649671 = 8649760
131 + 8649629 = 8649760
137 + 8649623 = 8649760
149 + 8649611 = 8649760
179 + 8649581 = 8649760

Showing the first eight; more decompositions exist.
