Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522450, here are decompositions:

11 + 522439 = 522450
37 + 522413 = 522450
41 + 522409 = 522450
59 + 522391 = 522450
67 + 522383 = 522450
79 + 522371 = 522450
113 + 522337 = 522450
127 + 522323 = 522450

Showing the first eight; more decompositions exist.
