Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643258, here are decompositions:

47 + 8643211 = 8643258
59 + 8643199 = 8643258
61 + 8643197 = 8643258
109 + 8643149 = 8643258
137 + 8643121 = 8643258
149 + 8643109 = 8643258
167 + 8643091 = 8643258
181 + 8643077 = 8643258

Showing the first eight; more decompositions exist.
