Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643450, here are decompositions:

7 + 8643443 = 8643450
17 + 8643433 = 8643450
41 + 8643409 = 8643450
83 + 8643367 = 8643450
107 + 8643343 = 8643450
113 + 8643337 = 8643450
163 + 8643287 = 8643450
227 + 8643223 = 8643450

Showing the first eight; more decompositions exist.
