Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643446, here are decompositions:

3 + 8643443 = 8643446
13 + 8643433 = 8643446
37 + 8643409 = 8643446
79 + 8643367 = 8643446
103 + 8643343 = 8643446
109 + 8643337 = 8643446
139 + 8643307 = 8643446
223 + 8643223 = 8643446

Showing the first eight; more decompositions exist.
