Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6890, here are decompositions:

7 + 6883 = 6890
19 + 6871 = 6890
61 + 6829 = 6890
67 + 6823 = 6890
97 + 6793 = 6890
109 + 6781 = 6890
127 + 6763 = 6890
157 + 6733 = 6890

Showing the first eight; more decompositions exist.
