Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6940, here are decompositions:

23 + 6917 = 6940
29 + 6911 = 6940
41 + 6899 = 6940
71 + 6869 = 6940
83 + 6857 = 6940
107 + 6833 = 6940
113 + 6827 = 6940
137 + 6803 = 6940

Showing the first eight; more decompositions exist.
