Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178466, here are decompositions:

19 + 178447 = 178466
73 + 178393 = 178466
139 + 178327 = 178466
283 + 178183 = 178466
349 + 178117 = 178466
373 + 178093 = 178466
397 + 178069 = 178466
487 + 177979 = 178466

Showing the first eight; more decompositions exist.
