Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005290, here are decompositions:

3 + 1005287 = 1005290
61 + 1005229 = 1005290
67 + 1005223 = 1005290
73 + 1005217 = 1005290
103 + 1005187 = 1005290
157 + 1005133 = 1005290
211 + 1005079 = 1005290
241 + 1005049 = 1005290

Showing the first eight; more decompositions exist.
