Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642352, here are decompositions:

23 + 8642329 = 8642352
71 + 8642281 = 8642352
163 + 8642189 = 8642352
179 + 8642173 = 8642352
193 + 8642159 = 8642352
211 + 8642141 = 8642352
233 + 8642119 = 8642352
241 + 8642111 = 8642352

Showing the first eight; more decompositions exist.
