Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 175530, here are decompositions:

7 + 175523 = 175530
11 + 175519 = 175530
31 + 175499 = 175530
37 + 175493 = 175530
67 + 175463 = 175530
83 + 175447 = 175530
97 + 175433 = 175530
127 + 175403 = 175530

Showing the first eight; more decompositions exist.
