Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 175518, here are decompositions:

19 + 175499 = 175518
37 + 175481 = 175518
71 + 175447 = 175518
107 + 175411 = 175518
127 + 175391 = 175518
157 + 175361 = 175518
191 + 175327 = 175518
227 + 175291 = 175518

Showing the first eight; more decompositions exist.
