Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643494, here are decompositions:

7 + 8643487 = 8643494
37 + 8643457 = 8643494
61 + 8643433 = 8643494
127 + 8643367 = 8643494
151 + 8643343 = 8643494
157 + 8643337 = 8643494
271 + 8643223 = 8643494
283 + 8643211 = 8643494

Showing the first eight; more decompositions exist.
