Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142194, here are decompositions:

5 + 142189 = 142194
11 + 142183 = 142194
37 + 142157 = 142194
43 + 142151 = 142194
71 + 142123 = 142194
83 + 142111 = 142194
97 + 142097 = 142194
127 + 142067 = 142194

Showing the first eight; more decompositions exist.
