Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641446, here are decompositions:

13 + 8641433 = 8641446
17 + 8641429 = 8641446
97 + 8641349 = 8641446
127 + 8641319 = 8641446
137 + 8641309 = 8641446
157 + 8641289 = 8641446
173 + 8641273 = 8641446
197 + 8641249 = 8641446

Showing the first eight; more decompositions exist.
