Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169142, here are decompositions:

13 + 169129 = 169142
31 + 169111 = 169142
73 + 169069 = 169142
79 + 169063 = 169142
139 + 169003 = 169142
151 + 168991 = 169142
199 + 168943 = 169142
229 + 168913 = 169142

Showing the first eight; more decompositions exist.
