Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6280, here are decompositions:

3 + 6277 = 6280
11 + 6269 = 6280
17 + 6263 = 6280
23 + 6257 = 6280
59 + 6221 = 6280
83 + 6197 = 6280
107 + 6173 = 6280
137 + 6143 = 6280

Showing the first eight; more decompositions exist.
