Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026420, here are decompositions:

7 + 1026413 = 1026420
13 + 1026407 = 1026420
19 + 1026401 = 1026420
29 + 1026391 = 1026420
37 + 1026383 = 1026420
61 + 1026359 = 1026420
89 + 1026331 = 1026420
107 + 1026313 = 1026420

Showing the first eight; more decompositions exist.
