Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531210, here are decompositions:

7 + 531203 = 531210
13 + 531197 = 531210
37 + 531173 = 531210
41 + 531169 = 531210
47 + 531163 = 531210
67 + 531143 = 531210
89 + 531121 = 531210
107 + 531103 = 531210

Showing the first eight; more decompositions exist.
