Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020420, here are decompositions:

7 + 1020413 = 1020420
13 + 1020407 = 1020420
19 + 1020401 = 1020420
31 + 1020389 = 1020420
41 + 1020379 = 1020420
59 + 1020361 = 1020420
67 + 1020353 = 1020420
83 + 1020337 = 1020420

Showing the first eight; more decompositions exist.
