Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1056420, here are decompositions:

19 + 1056401 = 1056420
41 + 1056379 = 1056420
47 + 1056373 = 1056420
59 + 1056361 = 1056420
67 + 1056353 = 1056420
73 + 1056347 = 1056420
97 + 1056323 = 1056420
103 + 1056317 = 1056420

Showing the first eight; more decompositions exist.
