Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 118280, here are decompositions:

3 + 118277 = 118280
7 + 118273 = 118280
31 + 118249 = 118280
61 + 118219 = 118280
67 + 118213 = 118280
109 + 118171 = 118280
199 + 118081 = 118280
223 + 118057 = 118280

Showing the first eight; more decompositions exist.
