Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627420, here are decompositions:

3 + 8627417 = 8627420
79 + 8627341 = 8627420
163 + 8627257 = 8627420
229 + 8627191 = 8627420
271 + 8627149 = 8627420
421 + 8626999 = 8627420
601 + 8626819 = 8627420
619 + 8626801 = 8627420

Showing the first eight; more decompositions exist.
