Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040740, here are decompositions:

23 + 1040717 = 1040740
83 + 1040657 = 1040740
89 + 1040651 = 1040740
251 + 1040489 = 1040740
257 + 1040483 = 1040740
293 + 1040447 = 1040740
353 + 1040387 = 1040740
359 + 1040381 = 1040740

Showing the first eight; more decompositions exist.
