Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142212, here are decompositions:

19 + 142193 = 142212
23 + 142189 = 142212
29 + 142183 = 142212
43 + 142169 = 142212
53 + 142159 = 142212
61 + 142151 = 142212
89 + 142123 = 142212
101 + 142111 = 142212

Showing the first eight; more decompositions exist.
