Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1056540, here are decompositions:

19 + 1056521 = 1056540
31 + 1056509 = 1056540
47 + 1056493 = 1056540
59 + 1056481 = 1056540
61 + 1056479 = 1056540
71 + 1056469 = 1056540
97 + 1056443 = 1056540
139 + 1056401 = 1056540

Showing the first eight; more decompositions exist.
