Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166790, here are decompositions:

7 + 166783 = 166790
67 + 166723 = 166790
97 + 166693 = 166790
163 + 166627 = 166790
181 + 166609 = 166790
193 + 166597 = 166790
223 + 166567 = 166790
229 + 166561 = 166790

Showing the first eight; more decompositions exist.
