Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178316, here are decompositions:

67 + 178249 = 178316
109 + 178207 = 178316
199 + 178117 = 178316
223 + 178093 = 178316
277 + 178039 = 178316
337 + 177979 = 178316
349 + 177967 = 178316
367 + 177949 = 178316

Showing the first eight; more decompositions exist.
