Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11280, here are decompositions:

7 + 11273 = 11280
19 + 11261 = 11280
23 + 11257 = 11280
29 + 11251 = 11280
37 + 11243 = 11280
41 + 11239 = 11280
67 + 11213 = 11280
83 + 11197 = 11280

Showing the first eight; more decompositions exist.
