Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166994, here are decompositions:

7 + 166987 = 166994
127 + 166867 = 166994
151 + 166843 = 166994
211 + 166783 = 166994
271 + 166723 = 166994
337 + 166657 = 166994
367 + 166627 = 166994
397 + 166597 = 166994

Showing the first eight; more decompositions exist.
