Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178132, here are decompositions:

5 + 178127 = 178132
29 + 178103 = 178132
41 + 178091 = 178132
131 + 178001 = 178132
179 + 177953 = 178132
239 + 177893 = 178132
293 + 177839 = 178132
389 + 177743 = 178132

Showing the first eight; more decompositions exist.
