Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6810, here are decompositions:

7 + 6803 = 6810
17 + 6793 = 6810
19 + 6791 = 6810
29 + 6781 = 6810
31 + 6779 = 6810
47 + 6763 = 6810
73 + 6737 = 6810
101 + 6709 = 6810

Showing the first eight; more decompositions exist.
