Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6510, here are decompositions:

19 + 6491 = 6510
29 + 6481 = 6510
37 + 6473 = 6510
41 + 6469 = 6510
59 + 6451 = 6510
61 + 6449 = 6510
83 + 6427 = 6510
89 + 6421 = 6510

Showing the first eight; more decompositions exist.
