Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040388, here are decompositions:

7 + 1040381 = 1040388
17 + 1040371 = 1040388
61 + 1040327 = 1040388
197 + 1040191 = 1040388
199 + 1040189 = 1040388
227 + 1040161 = 1040388
229 + 1040159 = 1040388
269 + 1040119 = 1040388

Showing the first eight; more decompositions exist.
