Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172132, here are decompositions:

5 + 172127 = 172132
53 + 172079 = 172132
83 + 172049 = 172132
101 + 172031 = 172132
131 + 172001 = 172132
251 + 171881 = 172132
263 + 171869 = 172132
269 + 171863 = 172132

Showing the first eight; more decompositions exist.
