Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164142, here are decompositions:

29 + 164113 = 164142
53 + 164089 = 164142
71 + 164071 = 164142
103 + 164039 = 164142
131 + 164011 = 164142
149 + 163993 = 164142
151 + 163991 = 164142
163 + 163979 = 164142

Showing the first eight; more decompositions exist.
