Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040380, here are decompositions:

41 + 1040339 = 1040380
53 + 1040327 = 1040380
191 + 1040189 = 1040380
197 + 1040183 = 1040380
227 + 1040153 = 1040380
239 + 1040141 = 1040380
311 + 1040069 = 1040380
359 + 1040021 = 1040380

Showing the first eight; more decompositions exist.
