Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178184, here are decompositions:

43 + 178141 = 178184
67 + 178117 = 178184
163 + 178021 = 178184
241 + 177943 = 178184
271 + 177913 = 178184
277 + 177907 = 178184
373 + 177811 = 178184
397 + 177787 = 178184

Showing the first eight; more decompositions exist.
