Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522644, here are decompositions:

7 + 522637 = 522644
43 + 522601 = 522644
103 + 522541 = 522644
127 + 522517 = 522644
271 + 522373 = 522644
307 + 522337 = 522644
433 + 522211 = 522644
487 + 522157 = 522644

Showing the first eight; more decompositions exist.
