Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530458, here are decompositions:

11 + 530447 = 530458
29 + 530429 = 530458
179 + 530279 = 530458
191 + 530267 = 530458
197 + 530261 = 530458
281 + 530177 = 530458
431 + 530027 = 530458
479 + 529979 = 530458

Showing the first eight; more decompositions exist.
