Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6458, here are decompositions:

7 + 6451 = 6458
31 + 6427 = 6458
37 + 6421 = 6458
61 + 6397 = 6458
79 + 6379 = 6458
97 + 6361 = 6458
157 + 6301 = 6458
181 + 6277 = 6458

Showing the first eight; more decompositions exist.
