Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521892, here are decompositions:

5 + 521887 = 521892
11 + 521881 = 521892
13 + 521879 = 521892
23 + 521869 = 521892
31 + 521861 = 521892
61 + 521831 = 521892
73 + 521819 = 521892
79 + 521813 = 521892

Showing the first eight; more decompositions exist.
