Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531152, here are decompositions:

19 + 531133 = 531152
31 + 531121 = 531152
73 + 531079 = 531152
109 + 531043 = 531152
163 + 530989 = 531152
241 + 530911 = 531152
283 + 530869 = 531152
379 + 530773 = 531152

Showing the first eight; more decompositions exist.
