Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6460, here are decompositions:

11 + 6449 = 6460
71 + 6389 = 6460
101 + 6359 = 6460
107 + 6353 = 6460
131 + 6329 = 6460
137 + 6323 = 6460
149 + 6311 = 6460
173 + 6287 = 6460

Showing the first eight; more decompositions exist.
