Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737986, here are decompositions:

7 + 8737979 = 8737986
43 + 8737943 = 8737986
53 + 8737933 = 8737986
113 + 8737873 = 8737986
137 + 8737849 = 8737986
157 + 8737829 = 8737986
197 + 8737789 = 8737986
223 + 8737763 = 8737986

Showing the first eight; more decompositions exist.
