Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166764, here are decompositions:

23 + 166741 = 166764
41 + 166723 = 166764
61 + 166703 = 166764
71 + 166693 = 166764
97 + 166667 = 166764
107 + 166657 = 166764
137 + 166627 = 166764
151 + 166613 = 166764

Showing the first eight; more decompositions exist.
