Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531382, here are decompositions:

23 + 531359 = 531382
29 + 531353 = 531382
83 + 531299 = 531382
101 + 531281 = 531382
179 + 531203 = 531382
239 + 531143 = 531382
281 + 531101 = 531382
311 + 531071 = 531382

Showing the first eight; more decompositions exist.
