Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005166, here are decompositions:

5 + 1005161 = 1005166
23 + 1005143 = 1005166
59 + 1005107 = 1005166
137 + 1005029 = 1005166
179 + 1004987 = 1005166
263 + 1004903 = 1005166
293 + 1004873 = 1005166
419 + 1004747 = 1005166

Showing the first eight; more decompositions exist.
