Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643486, here are decompositions:

29 + 8643457 = 8643486
43 + 8643443 = 8643486
53 + 8643433 = 8643486
127 + 8643359 = 8643486
149 + 8643337 = 8643486
179 + 8643307 = 8643486
199 + 8643287 = 8643486
263 + 8643223 = 8643486

Showing the first eight; more decompositions exist.
