Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513882, here are decompositions:

11 + 513871 = 513882
41 + 513841 = 513882
43 + 513839 = 513882
53 + 513829 = 513882
101 + 513781 = 513882
113 + 513769 = 513882
151 + 513731 = 513882
163 + 513719 = 513882

Showing the first eight; more decompositions exist.
