Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166672, here are decompositions:

3 + 166669 = 166672
5 + 166667 = 166672
29 + 166643 = 166672
41 + 166631 = 166672
53 + 166619 = 166672
59 + 166613 = 166672
71 + 166601 = 166672
101 + 166571 = 166672

Showing the first eight; more decompositions exist.
