Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726986, here are decompositions:

3 + 8726983 = 8726986
17 + 8726969 = 8726986
29 + 8726957 = 8726986
113 + 8726873 = 8726986
137 + 8726849 = 8726986
197 + 8726789 = 8726986
227 + 8726759 = 8726986
263 + 8726723 = 8726986

Showing the first eight; more decompositions exist.
