Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638446, here are decompositions:

43 + 8638403 = 8638446
67 + 8638379 = 8638446
73 + 8638373 = 8638446
97 + 8638349 = 8638446
107 + 8638339 = 8638446
109 + 8638337 = 8638446
127 + 8638319 = 8638446
163 + 8638283 = 8638446

Showing the first eight; more decompositions exist.
