Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178144, here are decompositions:

3 + 178141 = 178144
17 + 178127 = 178144
41 + 178103 = 178144
53 + 178091 = 178144
107 + 178037 = 178144
191 + 177953 = 178144
227 + 177917 = 178144
251 + 177893 = 178144

Showing the first eight; more decompositions exist.
