Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732720, here are decompositions:

43 + 8732677 = 8732720
67 + 8732653 = 8732720
79 + 8732641 = 8732720
127 + 8732593 = 8732720
349 + 8732371 = 8732720
421 + 8732299 = 8732720
463 + 8732257 = 8732720
523 + 8732197 = 8732720

Showing the first eight; more decompositions exist.
