Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737728, here are decompositions:

11 + 8737717 = 8737728
19 + 8737709 = 8737728
29 + 8737699 = 8737728
31 + 8737697 = 8737728
59 + 8737669 = 8737728
61 + 8737667 = 8737728
71 + 8737657 = 8737728
101 + 8737627 = 8737728

Showing the first eight; more decompositions exist.
