Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521898, here are decompositions:

11 + 521887 = 521898
17 + 521881 = 521898
19 + 521879 = 521898
29 + 521869 = 521898
37 + 521861 = 521898
67 + 521831 = 521898
79 + 521819 = 521898
89 + 521809 = 521898

Showing the first eight; more decompositions exist.
