Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142266, here are decompositions:

29 + 142237 = 142266
43 + 142223 = 142266
73 + 142193 = 142266
83 + 142183 = 142266
97 + 142169 = 142266
107 + 142159 = 142266
109 + 142157 = 142266
167 + 142099 = 142266

Showing the first eight; more decompositions exist.
