Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531150, here are decompositions:

7 + 531143 = 531150
17 + 531133 = 531150
29 + 531121 = 531150
47 + 531103 = 531150
71 + 531079 = 531150
79 + 531071 = 531150
107 + 531043 = 531150
127 + 531023 = 531150

Showing the first eight; more decompositions exist.
