Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162900, here are decompositions:

11 + 162889 = 162900
19 + 162881 = 162900
41 + 162859 = 162900
47 + 162853 = 162900
53 + 162847 = 162900
61 + 162839 = 162900
71 + 162829 = 162900
79 + 162821 = 162900

Showing the first eight; more decompositions exist.
