Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178348, here are decompositions:

41 + 178307 = 178348
47 + 178301 = 178348
59 + 178289 = 178348
89 + 178259 = 178348
101 + 178247 = 178348
179 + 178169 = 178348
197 + 178151 = 178348
257 + 178091 = 178348

Showing the first eight; more decompositions exist.
