Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531376, here are decompositions:

17 + 531359 = 531376
23 + 531353 = 531376
29 + 531347 = 531376
89 + 531287 = 531376
113 + 531263 = 531376
137 + 531239 = 531376
173 + 531203 = 531376
179 + 531197 = 531376

Showing the first eight; more decompositions exist.
