Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040686, here are decompositions:

29 + 1040657 = 1040686
89 + 1040597 = 1040686
107 + 1040579 = 1040686
197 + 1040489 = 1040686
239 + 1040447 = 1040686
347 + 1040339 = 1040686
359 + 1040327 = 1040686
467 + 1040219 = 1040686

Showing the first eight; more decompositions exist.
