Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626940, here are decompositions:

13 + 8626927 = 8626940
37 + 8626903 = 8626940
79 + 8626861 = 8626940
109 + 8626831 = 8626940
139 + 8626801 = 8626940
163 + 8626777 = 8626940
193 + 8626747 = 8626940
241 + 8626699 = 8626940

Showing the first eight; more decompositions exist.
