Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648662, here are decompositions:

131 + 8648531 = 8648662
149 + 8648513 = 8648662
293 + 8648369 = 8648662
563 + 8648099 = 8648662
569 + 8648093 = 8648662
683 + 8647979 = 8648662
773 + 8647889 = 8648662
839 + 8647823 = 8648662

Showing the first eight; more decompositions exist.
