Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531168, here are decompositions:

5 + 531163 = 531168
47 + 531121 = 531168
67 + 531101 = 531168
89 + 531079 = 531168
97 + 531071 = 531168
151 + 531017 = 531168
179 + 530989 = 531168
191 + 530977 = 531168

Showing the first eight; more decompositions exist.
