Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 175178, here are decompositions:

37 + 175141 = 175178
97 + 175081 = 175178
109 + 175069 = 175178
139 + 175039 = 175178
271 + 174907 = 175178
277 + 174901 = 175178
349 + 174829 = 175178
379 + 174799 = 175178

Showing the first eight; more decompositions exist.
