Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005126, here are decompositions:

19 + 1005107 = 1005126
47 + 1005079 = 1005126
53 + 1005073 = 1005126
97 + 1005029 = 1005126
107 + 1005019 = 1005126
113 + 1005013 = 1005126
139 + 1004987 = 1005126
149 + 1004977 = 1005126

Showing the first eight; more decompositions exist.
