Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166916, here are decompositions:

7 + 166909 = 166916
67 + 166849 = 166916
73 + 166843 = 166916
109 + 166807 = 166916
193 + 166723 = 166916
223 + 166693 = 166916
307 + 166609 = 166916
313 + 166603 = 166916

Showing the first eight; more decompositions exist.
