Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655384, here are decompositions:

13 + 8655371 = 8655384
41 + 8655343 = 8655384
53 + 8655331 = 8655384
71 + 8655313 = 8655384
97 + 8655287 = 8655384
167 + 8655217 = 8655384
173 + 8655211 = 8655384
211 + 8655173 = 8655384

Showing the first eight; more decompositions exist.
