Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531606, here are decompositions:

17 + 531589 = 531606
37 + 531569 = 531606
59 + 531547 = 531606
109 + 531497 = 531606
149 + 531457 = 531606
223 + 531383 = 531606
263 + 531343 = 531606
269 + 531337 = 531606

Showing the first eight; more decompositions exist.
