Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6410, here are decompositions:

13 + 6397 = 6410
31 + 6379 = 6410
37 + 6373 = 6410
43 + 6367 = 6410
67 + 6343 = 6410
73 + 6337 = 6410
109 + 6301 = 6410
139 + 6271 = 6410

Showing the first eight; more decompositions exist.
