Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166724, here are decompositions:

31 + 166693 = 166724
67 + 166657 = 166724
97 + 166627 = 166724
127 + 166597 = 166724
157 + 166567 = 166724
163 + 166561 = 166724
307 + 166417 = 166724
331 + 166393 = 166724

Showing the first eight; more decompositions exist.
