Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530404, here are decompositions:

3 + 530401 = 530404
11 + 530393 = 530404
71 + 530333 = 530404
101 + 530303 = 530404
107 + 530297 = 530404
137 + 530267 = 530404
167 + 530237 = 530404
227 + 530177 = 530404

Showing the first eight; more decompositions exist.
