Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142254, here are decompositions:

17 + 142237 = 142254
23 + 142231 = 142254
31 + 142223 = 142254
37 + 142217 = 142254
43 + 142211 = 142254
61 + 142193 = 142254
71 + 142183 = 142254
97 + 142157 = 142254

Showing the first eight; more decompositions exist.
