Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643378, here are decompositions:

11 + 8643367 = 8643378
19 + 8643359 = 8643378
41 + 8643337 = 8643378
61 + 8643317 = 8643378
71 + 8643307 = 8643378
97 + 8643281 = 8643378
167 + 8643211 = 8643378
179 + 8643199 = 8643378

Showing the first eight; more decompositions exist.
