Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642496, here are decompositions:

7 + 8642489 = 8642496
29 + 8642467 = 8642496
43 + 8642453 = 8642496
47 + 8642449 = 8642496
67 + 8642429 = 8642496
113 + 8642383 = 8642496
167 + 8642329 = 8642496
193 + 8642303 = 8642496

Showing the first eight; more decompositions exist.
