Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178372, here are decompositions:

11 + 178361 = 178372
23 + 178349 = 178372
71 + 178301 = 178372
83 + 178289 = 178372
113 + 178259 = 178372
149 + 178223 = 178372
269 + 178103 = 178372
281 + 178091 = 178372

Showing the first eight; more decompositions exist.
