Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732816, here are decompositions:

19 + 8732797 = 8732816
67 + 8732749 = 8732816
73 + 8732743 = 8732816
97 + 8732719 = 8732816
139 + 8732677 = 8732816
163 + 8732653 = 8732816
223 + 8732593 = 8732816
577 + 8732239 = 8732816

Showing the first eight; more decompositions exist.
