Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522420, here are decompositions:

7 + 522413 = 522420
11 + 522409 = 522420
29 + 522391 = 522420
37 + 522383 = 522420
47 + 522373 = 522420
83 + 522337 = 522420
97 + 522323 = 522420
103 + 522317 = 522420

Showing the first eight; more decompositions exist.
