Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530442, here are decompositions:

13 + 530429 = 530442
41 + 530401 = 530442
53 + 530389 = 530442
83 + 530359 = 530442
89 + 530353 = 530442
103 + 530339 = 530442
109 + 530333 = 530442
113 + 530329 = 530442

Showing the first eight; more decompositions exist.
