Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531348, here are decompositions:

5 + 531343 = 531348
11 + 531337 = 531348
17 + 531331 = 531348
61 + 531287 = 531348
67 + 531281 = 531348
109 + 531239 = 531348
151 + 531197 = 531348
179 + 531169 = 531348

Showing the first eight; more decompositions exist.
