Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 175290, here are decompositions:

13 + 175277 = 175290
23 + 175267 = 175290
29 + 175261 = 175290
61 + 175229 = 175290
79 + 175211 = 175290
149 + 175141 = 175290
211 + 175079 = 175290
223 + 175067 = 175290

Showing the first eight; more decompositions exist.
