Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531882, here are decompositions:

5 + 531877 = 531882
11 + 531871 = 531882
19 + 531863 = 531882
41 + 531841 = 531882
59 + 531823 = 531882
61 + 531821 = 531882
83 + 531799 = 531882
89 + 531793 = 531882

Showing the first eight; more decompositions exist.
