Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530430, here are decompositions:

29 + 530401 = 530430
37 + 530393 = 530430
41 + 530389 = 530430
71 + 530359 = 530430
97 + 530333 = 530430
101 + 530329 = 530430
127 + 530303 = 530430
137 + 530293 = 530430

Showing the first eight; more decompositions exist.
