Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732886, here are decompositions:

7 + 8732879 = 8732886
17 + 8732869 = 8732886
47 + 8732839 = 8732886
53 + 8732833 = 8732886
67 + 8732819 = 8732886
79 + 8732807 = 8732886
89 + 8732797 = 8732886
137 + 8732749 = 8732886

Showing the first eight; more decompositions exist.
