Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531006, here are decompositions:

17 + 530989 = 531006
23 + 530983 = 531006
29 + 530977 = 531006
37 + 530969 = 531006
59 + 530947 = 531006
109 + 530897 = 531006
137 + 530869 = 531006
149 + 530857 = 531006

Showing the first eight; more decompositions exist.
