Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5280, here are decompositions:

7 + 5273 = 5280
19 + 5261 = 5280
43 + 5237 = 5280
47 + 5233 = 5280
53 + 5227 = 5280
71 + 5209 = 5280
83 + 5197 = 5280
101 + 5179 = 5280

Showing the first eight; more decompositions exist.
