Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531002, here are decompositions:

13 + 530989 = 531002
19 + 530983 = 531002
151 + 530851 = 531002
229 + 530773 = 531002
271 + 530731 = 531002
349 + 530653 = 531002
463 + 530539 = 531002
601 + 530401 = 531002

Showing the first eight; more decompositions exist.
