Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178472, here are decompositions:

3 + 178469 = 178472
31 + 178441 = 178472
79 + 178393 = 178472
139 + 178333 = 178472
211 + 178261 = 178472
223 + 178249 = 178472
241 + 178231 = 178472
331 + 178141 = 178472

Showing the first eight; more decompositions exist.
