Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6500, here are decompositions:

19 + 6481 = 6500
31 + 6469 = 6500
73 + 6427 = 6500
79 + 6421 = 6500
103 + 6397 = 6500
127 + 6373 = 6500
139 + 6361 = 6500
157 + 6343 = 6500

Showing the first eight; more decompositions exist.
