Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005740, here are decompositions:

31 + 1005709 = 1005740
61 + 1005679 = 1005740
79 + 1005661 = 1005740
97 + 1005643 = 1005740
103 + 1005637 = 1005740
199 + 1005541 = 1005740
283 + 1005457 = 1005740
313 + 1005427 = 1005740

Showing the first eight; more decompositions exist.
