Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177280, here are decompositions:

11 + 177269 = 177280
23 + 177257 = 177280
41 + 177239 = 177280
71 + 177209 = 177280
107 + 177173 = 177280
113 + 177167 = 177280
149 + 177131 = 177280
167 + 177113 = 177280

Showing the first eight; more decompositions exist.
