Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531470, here are decompositions:

13 + 531457 = 531470
127 + 531343 = 531470
139 + 531331 = 531470
241 + 531229 = 531470
307 + 531163 = 531470
337 + 531133 = 531470
349 + 531121 = 531470
367 + 531103 = 531470

Showing the first eight; more decompositions exist.
