Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531354, here are decompositions:

7 + 531347 = 531354
11 + 531343 = 531354
17 + 531337 = 531354
23 + 531331 = 531354
67 + 531287 = 531354
73 + 531281 = 531354
101 + 531253 = 531354
151 + 531203 = 531354

Showing the first eight; more decompositions exist.
