Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643454, here are decompositions:

11 + 8643443 = 8643454
137 + 8643317 = 8643454
167 + 8643287 = 8643454
173 + 8643281 = 8643454
257 + 8643197 = 8643454
311 + 8643143 = 8643454
317 + 8643137 = 8643454
401 + 8643053 = 8643454

Showing the first eight; more decompositions exist.
