Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6980, here are decompositions:

3 + 6977 = 6980
13 + 6967 = 6980
19 + 6961 = 6980
31 + 6949 = 6980
73 + 6907 = 6980
97 + 6883 = 6980
109 + 6871 = 6980
139 + 6841 = 6980

Showing the first eight; more decompositions exist.
