Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 160666, here are decompositions:

3 + 160663 = 160666
17 + 160649 = 160666
29 + 160637 = 160666
47 + 160619 = 160666
83 + 160583 = 160666
113 + 160553 = 160666
167 + 160499 = 160666
257 + 160409 = 160666

Showing the first eight; more decompositions exist.
