Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522442, here are decompositions:

3 + 522439 = 522442
29 + 522413 = 522442
59 + 522383 = 522442
71 + 522371 = 522442
191 + 522251 = 522442
251 + 522191 = 522442
281 + 522161 = 522442
359 + 522083 = 522442

Showing the first eight; more decompositions exist.
