Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737128, here are decompositions:

11 + 8737117 = 8737128
17 + 8737111 = 8737128
31 + 8737097 = 8737128
61 + 8737067 = 8737128
67 + 8737061 = 8737128
79 + 8737049 = 8737128
89 + 8737039 = 8737128
107 + 8737021 = 8737128

Showing the first eight; more decompositions exist.
