Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020384, here are decompositions:

5 + 1020379 = 1020384
23 + 1020361 = 1020384
31 + 1020353 = 1020384
47 + 1020337 = 1020384
83 + 1020301 = 1020384
137 + 1020247 = 1020384
151 + 1020233 = 1020384
227 + 1020157 = 1020384

Showing the first eight; more decompositions exist.
