Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168226, here are decompositions:

29 + 168197 = 168226
83 + 168143 = 168226
137 + 168089 = 168226
197 + 168029 = 168226
239 + 167987 = 168226
347 + 167879 = 168226
353 + 167873 = 168226
449 + 167777 = 168226

Showing the first eight; more decompositions exist.
