Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637446, here are decompositions:

19 + 8637427 = 8637446
67 + 8637379 = 8637446
73 + 8637373 = 8637446
109 + 8637337 = 8637446
127 + 8637319 = 8637446
157 + 8637289 = 8637446
193 + 8637253 = 8637446
199 + 8637247 = 8637446

Showing the first eight; more decompositions exist.
