Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020404, here are decompositions:

3 + 1020401 = 1020404
43 + 1020361 = 1020404
67 + 1020337 = 1020404
103 + 1020301 = 1020404
157 + 1020247 = 1020404
181 + 1020223 = 1020404
241 + 1020163 = 1020404
367 + 1020037 = 1020404

Showing the first eight; more decompositions exist.
