Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 175180, here are decompositions:

101 + 175079 = 175180
113 + 175067 = 175180
167 + 175013 = 175180
191 + 174989 = 175180
251 + 174929 = 175180
263 + 174917 = 175180
359 + 174821 = 175180
419 + 174761 = 175180

Showing the first eight; more decompositions exist.
