Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1056428, here are decompositions:

67 + 1056361 = 1056428
157 + 1056271 = 1056428
181 + 1056247 = 1056428
211 + 1056217 = 1056428
367 + 1056061 = 1056428
379 + 1056049 = 1056428
409 + 1056019 = 1056428
421 + 1056007 = 1056428

Showing the first eight; more decompositions exist.
