Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1016388, here are decompositions:

17 + 1016371 = 1016388
29 + 1016359 = 1016388
31 + 1016357 = 1016388
47 + 1016341 = 1016388
151 + 1016237 = 1016388
157 + 1016231 = 1016388
167 + 1016221 = 1016388
229 + 1016159 = 1016388

Showing the first eight; more decompositions exist.
