Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7686, here are decompositions:

5 + 7681 = 7686
13 + 7673 = 7686
17 + 7669 = 7686
37 + 7649 = 7686
43 + 7643 = 7686
47 + 7639 = 7686
79 + 7607 = 7686
83 + 7603 = 7686

Showing the first eight; more decompositions exist.
