Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6812, here are decompositions:

19 + 6793 = 6812
31 + 6781 = 6812
79 + 6733 = 6812
103 + 6709 = 6812
109 + 6703 = 6812
139 + 6673 = 6812
151 + 6661 = 6812
193 + 6619 = 6812

Showing the first eight; more decompositions exist.
