Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6920, here are decompositions:

3 + 6917 = 6920
13 + 6907 = 6920
37 + 6883 = 6920
79 + 6841 = 6920
97 + 6823 = 6920
127 + 6793 = 6920
139 + 6781 = 6920
157 + 6763 = 6920

Showing the first eight; more decompositions exist.
