Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6872, here are decompositions:

3 + 6869 = 6872
31 + 6841 = 6872
43 + 6829 = 6872
79 + 6793 = 6872
109 + 6763 = 6872
139 + 6733 = 6872
163 + 6709 = 6872
181 + 6691 = 6872

Showing the first eight; more decompositions exist.
