Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628416, here are decompositions:

67 + 8628349 = 8628416
229 + 8628187 = 8628416
367 + 8628049 = 8628416
397 + 8628019 = 8628416
409 + 8628007 = 8628416
439 + 8627977 = 8628416
463 + 8627953 = 8628416
523 + 8627893 = 8628416

Showing the first eight; more decompositions exist.
