Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638416, here are decompositions:

5 + 8638411 = 8638416
13 + 8638403 = 8638416
37 + 8638379 = 8638416
43 + 8638373 = 8638416
67 + 8638349 = 8638416
79 + 8638337 = 8638416
89 + 8638327 = 8638416
97 + 8638319 = 8638416

Showing the first eight; more decompositions exist.
