Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531844, here are decompositions:

3 + 531841 = 531844
11 + 531833 = 531844
17 + 531827 = 531844
23 + 531821 = 531844
113 + 531731 = 531844
233 + 531611 = 531844
263 + 531581 = 531844
293 + 531551 = 531844

Showing the first eight; more decompositions exist.
