Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 175140, here are decompositions:

11 + 175129 = 175140
37 + 175103 = 175140
59 + 175081 = 175140
61 + 175079 = 175140
71 + 175069 = 175140
73 + 175067 = 175140
79 + 175061 = 175140
101 + 175039 = 175140

Showing the first eight; more decompositions exist.
