Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1016380, here are decompositions:

23 + 1016357 = 1016380
41 + 1016339 = 1016380
149 + 1016231 = 1016380
179 + 1016201 = 1016380
227 + 1016153 = 1016380
257 + 1016123 = 1016380
269 + 1016111 = 1016380
311 + 1016069 = 1016380

Showing the first eight; more decompositions exist.
