Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732864, here are decompositions:

3 + 8732861 = 8732864
31 + 8732833 = 8732864
67 + 8732797 = 8732864
211 + 8732653 = 8732864
223 + 8732641 = 8732864
271 + 8732593 = 8732864
313 + 8732551 = 8732864
433 + 8732431 = 8732864

Showing the first eight; more decompositions exist.
