Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1030640, here are decompositions:

3 + 1030637 = 1030640
97 + 1030543 = 1030640
103 + 1030537 = 1030640
199 + 1030441 = 1030640
211 + 1030429 = 1030640
223 + 1030417 = 1030640
229 + 1030411 = 1030640
271 + 1030369 = 1030640

Showing the first eight; more decompositions exist.
