Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626928, here are decompositions:

67 + 8626861 = 8626928
97 + 8626831 = 8626928
109 + 8626819 = 8626928
127 + 8626801 = 8626928
151 + 8626777 = 8626928
181 + 8626747 = 8626928
229 + 8626699 = 8626928
307 + 8626621 = 8626928

Showing the first eight; more decompositions exist.
