Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6450, here are decompositions:

23 + 6427 = 6450
29 + 6421 = 6450
53 + 6397 = 6450
61 + 6389 = 6450
71 + 6379 = 6450
83 + 6367 = 6450
89 + 6361 = 6450
97 + 6353 = 6450

Showing the first eight; more decompositions exist.
