Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522812, here are decompositions:

109 + 522703 = 522812
139 + 522673 = 522812
151 + 522661 = 522812
211 + 522601 = 522812
271 + 522541 = 522812
373 + 522439 = 522812
421 + 522391 = 522812
439 + 522373 = 522812

Showing the first eight; more decompositions exist.
