Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531012, here are decompositions:

23 + 530989 = 531012
29 + 530983 = 531012
43 + 530969 = 531012
101 + 530911 = 531012
151 + 530861 = 531012
179 + 530833 = 531012
239 + 530773 = 531012
269 + 530743 = 531012

Showing the first eight; more decompositions exist.
