Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142182, here are decompositions:

13 + 142169 = 142182
23 + 142159 = 142182
31 + 142151 = 142182
59 + 142123 = 142182
71 + 142111 = 142182
83 + 142099 = 142182
151 + 142031 = 142182
163 + 142019 = 142182

Showing the first eight; more decompositions exist.
