Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531484, here are decompositions:

3 + 531481 = 531484
101 + 531383 = 531484
131 + 531353 = 531484
137 + 531347 = 531484
197 + 531287 = 531484
281 + 531203 = 531484
311 + 531173 = 531484
383 + 531101 = 531484

Showing the first eight; more decompositions exist.
