Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531394, here are decompositions:

11 + 531383 = 531394
41 + 531353 = 531394
47 + 531347 = 531394
107 + 531287 = 531394
113 + 531281 = 531394
131 + 531263 = 531394
191 + 531203 = 531394
197 + 531197 = 531394

Showing the first eight; more decompositions exist.
