Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522740, here are decompositions:

3 + 522737 = 522740
37 + 522703 = 522740
61 + 522679 = 522740
67 + 522673 = 522740
79 + 522661 = 522740
103 + 522637 = 522740
139 + 522601 = 522740
199 + 522541 = 522740

Showing the first eight; more decompositions exist.
