Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6990, here are decompositions:

7 + 6983 = 6990
13 + 6977 = 6990
19 + 6971 = 6990
23 + 6967 = 6990
29 + 6961 = 6990
31 + 6959 = 6990
41 + 6949 = 6990
43 + 6947 = 6990

Showing the first eight; more decompositions exist.
