Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166354, here are decompositions:

3 + 166351 = 166354
5 + 166349 = 166354
53 + 166301 = 166354
107 + 166247 = 166354
197 + 166157 = 166354
311 + 166043 = 166354
467 + 165887 = 166354
521 + 165833 = 166354

Showing the first eight; more decompositions exist.
