Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522398, here are decompositions:

7 + 522391 = 522398
61 + 522337 = 522398
109 + 522289 = 522398
139 + 522259 = 522398
199 + 522199 = 522398
241 + 522157 = 522398
271 + 522127 = 522398
337 + 522061 = 522398

Showing the first eight; more decompositions exist.
