Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1056538, here are decompositions:

17 + 1056521 = 1056538
29 + 1056509 = 1056538
59 + 1056479 = 1056538
137 + 1056401 = 1056538
167 + 1056371 = 1056538
191 + 1056347 = 1056538
227 + 1056311 = 1056538
251 + 1056287 = 1056538

Showing the first eight; more decompositions exist.
