Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672216, here are decompositions:

13 + 8672203 = 8672216
229 + 8671987 = 8672216
379 + 8671837 = 8672216
547 + 8671669 = 8672216
577 + 8671639 = 8672216
643 + 8671573 = 8672216
769 + 8671447 = 8672216
823 + 8671393 = 8672216

Showing the first eight; more decompositions exist.
