Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 160142, here are decompositions:

61 + 160081 = 160142
109 + 160033 = 160142
163 + 159979 = 160142
211 + 159931 = 160142
271 + 159871 = 160142
331 + 159811 = 160142
349 + 159793 = 160142
373 + 159769 = 160142

Showing the first eight; more decompositions exist.
