Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 175666, here are decompositions:

3 + 175663 = 175666
17 + 175649 = 175666
167 + 175499 = 175666
173 + 175493 = 175666
233 + 175433 = 175666
263 + 175403 = 175666
317 + 175349 = 175666
389 + 175277 = 175666

Showing the first eight; more decompositions exist.
