Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020290, here are decompositions:

31 + 1020259 = 1020290
43 + 1020247 = 1020290
67 + 1020223 = 1020290
127 + 1020163 = 1020290
181 + 1020109 = 1020290
211 + 1020079 = 1020290
241 + 1020049 = 1020290
277 + 1020013 = 1020290

Showing the first eight; more decompositions exist.
