Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158142, here are decompositions:

13 + 158129 = 158142
29 + 158113 = 158142
71 + 158071 = 158142
113 + 158029 = 158142
139 + 158003 = 158142
151 + 157991 = 158142
191 + 157951 = 158142
211 + 157931 = 158142

Showing the first eight; more decompositions exist.
