Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 160180, here are decompositions:

11 + 160169 = 160180
17 + 160163 = 160180
89 + 160091 = 160180
101 + 160079 = 160180
107 + 160073 = 160180
131 + 160049 = 160180
149 + 160031 = 160180
179 + 160001 = 160180

Showing the first eight; more decompositions exist.
