Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 175280, here are decompositions:

3 + 175277 = 175280
13 + 175267 = 175280
19 + 175261 = 175280
139 + 175141 = 175280
151 + 175129 = 175280
199 + 175081 = 175280
211 + 175069 = 175280
241 + 175039 = 175280

Showing the first eight; more decompositions exist.
