Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522628, here are decompositions:

5 + 522623 = 522628
59 + 522569 = 522628
107 + 522521 = 522628
131 + 522497 = 522628
149 + 522479 = 522628
179 + 522449 = 522628
257 + 522371 = 522628
311 + 522317 = 522628

Showing the first eight; more decompositions exist.
