Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643252, here are decompositions:

29 + 8643223 = 8643252
41 + 8643211 = 8643252
43 + 8643209 = 8643252
53 + 8643199 = 8643252
71 + 8643181 = 8643252
103 + 8643149 = 8643252
109 + 8643143 = 8643252
131 + 8643121 = 8643252

Showing the first eight; more decompositions exist.
