Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 174178, here are decompositions:

29 + 174149 = 174178
41 + 174137 = 174178
101 + 174077 = 174178
107 + 174071 = 174178
131 + 174047 = 174178
197 + 173981 = 174178
269 + 173909 = 174178
281 + 173897 = 174178

Showing the first eight; more decompositions exist.
