Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 175128, here are decompositions:

47 + 175081 = 175128
59 + 175069 = 175128
61 + 175067 = 175128
67 + 175061 = 175128
89 + 175039 = 175128
137 + 174991 = 175128
139 + 174989 = 175128
197 + 174931 = 175128

Showing the first eight; more decompositions exist.
