Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531008, here are decompositions:

19 + 530989 = 531008
31 + 530977 = 531008
61 + 530947 = 531008
97 + 530911 = 531008
139 + 530869 = 531008
151 + 530857 = 531008
157 + 530851 = 531008
211 + 530797 = 531008

Showing the first eight; more decompositions exist.
