Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530532, here are decompositions:

5 + 530527 = 530532
19 + 530513 = 530532
31 + 530501 = 530532
89 + 530443 = 530532
103 + 530429 = 530532
131 + 530401 = 530532
139 + 530393 = 530532
173 + 530359 = 530532

Showing the first eight; more decompositions exist.
