Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531324, here are decompositions:

37 + 531287 = 531324
43 + 531281 = 531324
61 + 531263 = 531324
71 + 531253 = 531324
127 + 531197 = 531324
151 + 531173 = 531324
181 + 531143 = 531324
191 + 531133 = 531324

Showing the first eight; more decompositions exist.
