Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530406, here are decompositions:

5 + 530401 = 530406
13 + 530393 = 530406
17 + 530389 = 530406
47 + 530359 = 530406
53 + 530353 = 530406
67 + 530339 = 530406
73 + 530333 = 530406
103 + 530303 = 530406

Showing the first eight; more decompositions exist.
