Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 160660, here are decompositions:

11 + 160649 = 160660
23 + 160637 = 160660
41 + 160619 = 160660
107 + 160553 = 160660
179 + 160481 = 160660
251 + 160409 = 160660
257 + 160403 = 160660
263 + 160397 = 160660

Showing the first eight; more decompositions exist.
