Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531342, here are decompositions:

5 + 531337 = 531342
11 + 531331 = 531342
43 + 531299 = 531342
61 + 531281 = 531342
79 + 531263 = 531342
89 + 531253 = 531342
103 + 531239 = 531342
113 + 531229 = 531342

Showing the first eight; more decompositions exist.
