Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1056530, here are decompositions:

37 + 1056493 = 1056530
61 + 1056469 = 1056530
67 + 1056463 = 1056530
151 + 1056379 = 1056530
157 + 1056373 = 1056530
283 + 1056247 = 1056530
313 + 1056217 = 1056530
421 + 1056109 = 1056530

Showing the first eight; more decompositions exist.
