Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7806, here are decompositions:

13 + 7793 = 7806
17 + 7789 = 7806
47 + 7759 = 7806
53 + 7753 = 7806
79 + 7727 = 7806
83 + 7723 = 7806
89 + 7717 = 7806
103 + 7703 = 7806

Showing the first eight; more decompositions exist.
