Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166920, here are decompositions:

11 + 166909 = 166920
53 + 166867 = 166920
59 + 166861 = 166920
67 + 166853 = 166920
71 + 166849 = 166920
73 + 166847 = 166920
79 + 166841 = 166920
97 + 166823 = 166920

Showing the first eight; more decompositions exist.
