Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168284, here are decompositions:

3 + 168281 = 168284
7 + 168277 = 168284
31 + 168253 = 168284
37 + 168247 = 168284
73 + 168211 = 168284
157 + 168127 = 168284
241 + 168043 = 168284
271 + 168013 = 168284

Showing the first eight; more decompositions exist.
