Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531486, here are decompositions:

5 + 531481 = 531486
29 + 531457 = 531486
103 + 531383 = 531486
127 + 531359 = 531486
139 + 531347 = 531486
149 + 531337 = 531486
199 + 531287 = 531486
223 + 531263 = 531486

Showing the first eight; more decompositions exist.
