Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 563280, here are decompositions:

17 + 563263 = 563280
31 + 563249 = 563280
61 + 563219 = 563280
83 + 563197 = 563280
97 + 563183 = 563280
127 + 563153 = 563280
131 + 563149 = 563280
149 + 563131 = 563280

Showing the first eight; more decompositions exist.
