Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178186, here are decompositions:

3 + 178183 = 178186
17 + 178169 = 178186
59 + 178127 = 178186
83 + 178103 = 178186
149 + 178037 = 178186
233 + 177953 = 178186
257 + 177929 = 178186
269 + 177917 = 178186

Showing the first eight; more decompositions exist.
