Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643464, here are decompositions:

7 + 8643457 = 8643464
31 + 8643433 = 8643464
97 + 8643367 = 8643464
127 + 8643337 = 8643464
157 + 8643307 = 8643464
241 + 8643223 = 8643464
283 + 8643181 = 8643464
331 + 8643133 = 8643464

Showing the first eight; more decompositions exist.
