Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531406, here are decompositions:

23 + 531383 = 531406
47 + 531359 = 531406
53 + 531353 = 531406
59 + 531347 = 531406
107 + 531299 = 531406
167 + 531239 = 531406
233 + 531173 = 531406
263 + 531143 = 531406

Showing the first eight; more decompositions exist.
