Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531010, here are decompositions:

41 + 530969 = 531010
113 + 530897 = 531010
149 + 530861 = 531010
167 + 530843 = 531010
173 + 530837 = 531010
257 + 530753 = 531010
269 + 530741 = 531010
317 + 530693 = 531010

Showing the first eight; more decompositions exist.
