Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005298, here are decompositions:

5 + 1005293 = 1005298
11 + 1005287 = 1005298
29 + 1005269 = 1005298
59 + 1005239 = 1005298
89 + 1005209 = 1005298
137 + 1005161 = 1005298
167 + 1005131 = 1005298
191 + 1005107 = 1005298

Showing the first eight; more decompositions exist.
