Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6446, here are decompositions:

19 + 6427 = 6446
67 + 6379 = 6446
73 + 6373 = 6446
79 + 6367 = 6446
103 + 6343 = 6446
109 + 6337 = 6446
199 + 6247 = 6446
229 + 6217 = 6446

Showing the first eight; more decompositions exist.
