Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627138, here are decompositions:

19 + 8627119 = 8627138
109 + 8627029 = 8627138
139 + 8626999 = 8627138
211 + 8626927 = 8627138
277 + 8626861 = 8627138
307 + 8626831 = 8627138
337 + 8626801 = 8627138
439 + 8626699 = 8627138

Showing the first eight; more decompositions exist.
