Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005836, here are decompositions:

3 + 1005833 = 1005836
127 + 1005709 = 1005836
157 + 1005679 = 1005836
193 + 1005643 = 1005836
199 + 1005637 = 1005836
283 + 1005553 = 1005836
379 + 1005457 = 1005836
397 + 1005439 = 1005836

Showing the first eight; more decompositions exist.
