Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522426, here are decompositions:

13 + 522413 = 522426
17 + 522409 = 522426
43 + 522383 = 522426
53 + 522373 = 522426
89 + 522337 = 522426
103 + 522323 = 522426
109 + 522317 = 522426
137 + 522289 = 522426

Showing the first eight; more decompositions exist.
