Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166826, here are decompositions:

3 + 166823 = 166826
19 + 166807 = 166826
43 + 166783 = 166826
103 + 166723 = 166826
157 + 166669 = 166826
199 + 166627 = 166826
223 + 166603 = 166826
229 + 166597 = 166826

Showing the first eight; more decompositions exist.
