Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 175220, here are decompositions:

79 + 175141 = 175220
139 + 175081 = 175220
151 + 175069 = 175220
181 + 175039 = 175220
229 + 174991 = 175220
277 + 174943 = 175220
313 + 174907 = 175220
421 + 174799 = 175220

Showing the first eight; more decompositions exist.
