Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522438, here are decompositions:

29 + 522409 = 522438
47 + 522391 = 522438
67 + 522371 = 522438
101 + 522337 = 522438
149 + 522289 = 522438
157 + 522281 = 522438
179 + 522259 = 522438
199 + 522239 = 522438

Showing the first eight; more decompositions exist.
