Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6818, here are decompositions:

37 + 6781 = 6818
109 + 6709 = 6818
127 + 6691 = 6818
139 + 6679 = 6818
157 + 6661 = 6818
181 + 6637 = 6818
199 + 6619 = 6818
211 + 6607 = 6818

Showing the first eight; more decompositions exist.
