Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531498, here are decompositions:

17 + 531481 = 531498
41 + 531457 = 531498
139 + 531359 = 531498
151 + 531347 = 531498
167 + 531331 = 531498
199 + 531299 = 531498
211 + 531287 = 531498
269 + 531229 = 531498

Showing the first eight; more decompositions exist.
