Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 175988, here are decompositions:

79 + 175909 = 175988
97 + 175891 = 175988
151 + 175837 = 175988
229 + 175759 = 175988
367 + 175621 = 175988
541 + 175447 = 175988
577 + 175411 = 175988
661 + 175327 = 175988

Showing the first eight; more decompositions exist.
