Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531718, here are decompositions:

17 + 531701 = 531718
29 + 531689 = 531718
107 + 531611 = 531718
137 + 531581 = 531718
149 + 531569 = 531718
167 + 531551 = 531718
197 + 531521 = 531718
359 + 531359 = 531718

Showing the first eight; more decompositions exist.
