Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531366, here are decompositions:

7 + 531359 = 531366
13 + 531353 = 531366
19 + 531347 = 531366
23 + 531343 = 531366
29 + 531337 = 531366
67 + 531299 = 531366
79 + 531287 = 531366
103 + 531263 = 531366

Showing the first eight; more decompositions exist.
