Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168282, here are decompositions:

5 + 168277 = 168282
13 + 168269 = 168282
19 + 168263 = 168282
29 + 168253 = 168282
71 + 168211 = 168282
89 + 168193 = 168282
131 + 168151 = 168282
139 + 168143 = 168282

Showing the first eight; more decompositions exist.
