Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166698, here are decompositions:

5 + 166693 = 166698
19 + 166679 = 166698
29 + 166669 = 166698
31 + 166667 = 166698
41 + 166657 = 166698
67 + 166631 = 166698
71 + 166627 = 166698
79 + 166619 = 166698

Showing the first eight; more decompositions exist.
