Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168178, here are decompositions:

89 + 168089 = 168178
107 + 168071 = 168178
149 + 168029 = 168178
191 + 167987 = 168178
317 + 167861 = 168178
401 + 167777 = 168178
419 + 167759 = 168178
431 + 167747 = 168178

Showing the first eight; more decompositions exist.
