Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629648, here are decompositions:

11 + 8629637 = 8629648
239 + 8629409 = 8629648
449 + 8629199 = 8629648
479 + 8629169 = 8629648
491 + 8629157 = 8629648
509 + 8629139 = 8629648
569 + 8629079 = 8629648
857 + 8628791 = 8629648

Showing the first eight; more decompositions exist.
