Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530542, here are decompositions:

3 + 530539 = 530542
11 + 530531 = 530542
29 + 530513 = 530542
41 + 530501 = 530542
113 + 530429 = 530542
149 + 530393 = 530542
239 + 530303 = 530542
263 + 530279 = 530542

Showing the first eight; more decompositions exist.
