Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522738, here are decompositions:

19 + 522719 = 522738
31 + 522707 = 522738
59 + 522679 = 522738
61 + 522677 = 522738
79 + 522659 = 522738
101 + 522637 = 522738
137 + 522601 = 522738
197 + 522541 = 522738

Showing the first eight; more decompositions exist.
