Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005122, here are decompositions:

43 + 1005079 = 1005122
73 + 1005049 = 1005122
103 + 1005019 = 1005122
109 + 1005013 = 1005122
211 + 1004911 = 1005122
373 + 1004749 = 1005122
379 + 1004743 = 1005122
463 + 1004659 = 1005122

Showing the first eight; more decompositions exist.
