Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6466, here are decompositions:

17 + 6449 = 6466
107 + 6359 = 6466
113 + 6353 = 6466
137 + 6329 = 6466
149 + 6317 = 6466
167 + 6299 = 6466
179 + 6287 = 6466
197 + 6269 = 6466

Showing the first eight; more decompositions exist.
