Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166928, here are decompositions:

19 + 166909 = 166928
61 + 166867 = 166928
67 + 166861 = 166928
79 + 166849 = 166928
271 + 166657 = 166928
331 + 166597 = 166928
367 + 166561 = 166928
457 + 166471 = 166928

Showing the first eight; more decompositions exist.
