Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166662, here are decompositions:

5 + 166657 = 166662
19 + 166643 = 166662
31 + 166631 = 166662
43 + 166619 = 166662
53 + 166609 = 166662
59 + 166603 = 166662
61 + 166601 = 166662
101 + 166561 = 166662

Showing the first eight; more decompositions exist.
