Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522920, here are decompositions:

37 + 522883 = 522920
67 + 522853 = 522920
109 + 522811 = 522920
157 + 522763 = 522920
163 + 522757 = 522920
241 + 522679 = 522920
283 + 522637 = 522920
367 + 522553 = 522920

Showing the first eight; more decompositions exist.
