Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642396, here are decompositions:

13 + 8642383 = 8642396
67 + 8642329 = 8642396
199 + 8642197 = 8642396
223 + 8642173 = 8642396
277 + 8642119 = 8642396
337 + 8642059 = 8642396
409 + 8641987 = 8642396
439 + 8641957 = 8642396

Showing the first eight; more decompositions exist.
