Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522530, here are decompositions:

7 + 522523 = 522530
13 + 522517 = 522530
61 + 522469 = 522530
139 + 522391 = 522530
157 + 522373 = 522530
193 + 522337 = 522530
241 + 522289 = 522530
271 + 522259 = 522530

Showing the first eight; more decompositions exist.
