Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021018, here are decompositions:

17 + 1021001 = 1021018
29 + 1020989 = 1021018
41 + 1020977 = 1021018
59 + 1020959 = 1021018
137 + 1020881 = 1021018
179 + 1020839 = 1021018
191 + 1020827 = 1021018
197 + 1020821 = 1021018

Showing the first eight; more decompositions exist.
