Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8653728, here are decompositions:

11 + 8653717 = 8653728
19 + 8653709 = 8653728
29 + 8653699 = 8653728
37 + 8653691 = 8653728
59 + 8653669 = 8653728
71 + 8653657 = 8653728
101 + 8653627 = 8653728
137 + 8653591 = 8653728

Showing the first eight; more decompositions exist.
