Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6480, here are decompositions:

7 + 6473 = 6480
11 + 6469 = 6480
29 + 6451 = 6480
31 + 6449 = 6480
53 + 6427 = 6480
59 + 6421 = 6480
83 + 6397 = 6480
101 + 6379 = 6480

Showing the first eight; more decompositions exist.
