Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142206, here are decompositions:

13 + 142193 = 142206
17 + 142189 = 142206
23 + 142183 = 142206
37 + 142169 = 142206
47 + 142159 = 142206
83 + 142123 = 142206
107 + 142099 = 142206
109 + 142097 = 142206

Showing the first eight; more decompositions exist.
