Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6986, here are decompositions:

3 + 6983 = 6986
19 + 6967 = 6986
37 + 6949 = 6986
79 + 6907 = 6986
103 + 6883 = 6986
157 + 6829 = 6986
163 + 6823 = 6986
193 + 6793 = 6986

Showing the first eight; more decompositions exist.
