Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642358, here are decompositions:

29 + 8642329 = 8642358
199 + 8642159 = 8642358
211 + 8642147 = 8642358
239 + 8642119 = 8642358
251 + 8642107 = 8642358
281 + 8642077 = 8642358
331 + 8642027 = 8642358
367 + 8641991 = 8642358

Showing the first eight; more decompositions exist.
