Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142164, here are decompositions:

5 + 142159 = 142164
7 + 142157 = 142164
13 + 142151 = 142164
41 + 142123 = 142164
53 + 142111 = 142164
67 + 142097 = 142164
97 + 142067 = 142164
103 + 142061 = 142164

Showing the first eight; more decompositions exist.
