Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626938, here are decompositions:

11 + 8626927 = 8626938
37 + 8626901 = 8626938
97 + 8626841 = 8626938
107 + 8626831 = 8626938
127 + 8626811 = 8626938
137 + 8626801 = 8626938
191 + 8626747 = 8626938
239 + 8626699 = 8626938

Showing the first eight; more decompositions exist.
