Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643470, here are decompositions:

13 + 8643457 = 8643470
37 + 8643433 = 8643470
61 + 8643409 = 8643470
103 + 8643367 = 8643470
127 + 8643343 = 8643470
163 + 8643307 = 8643470
271 + 8643199 = 8643470
337 + 8643133 = 8643470

Showing the first eight; more decompositions exist.
