Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647396, here are decompositions:

3 + 8647393 = 8647396
5 + 8647391 = 8647396
29 + 8647367 = 8647396
47 + 8647349 = 8647396
167 + 8647229 = 8647396
239 + 8647157 = 8647396
257 + 8647139 = 8647396
269 + 8647127 = 8647396

Showing the first eight; more decompositions exist.
