Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6988, here are decompositions:

5 + 6983 = 6988
11 + 6977 = 6988
17 + 6971 = 6988
29 + 6959 = 6988
41 + 6947 = 6988
71 + 6917 = 6988
89 + 6899 = 6988
131 + 6857 = 6988

Showing the first eight; more decompositions exist.
