Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020260, here are decompositions:

13 + 1020247 = 1020260
37 + 1020223 = 1020260
97 + 1020163 = 1020260
103 + 1020157 = 1020260
151 + 1020109 = 1020260
181 + 1020079 = 1020260
211 + 1020049 = 1020260
223 + 1020037 = 1020260

Showing the first eight; more decompositions exist.
