Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78986, here are decompositions:

7 + 78979 = 78986
67 + 78919 = 78986
97 + 78889 = 78986
109 + 78877 = 78986
163 + 78823 = 78986
199 + 78787 = 78986
337 + 78649 = 78986
379 + 78607 = 78986

Showing the first eight; more decompositions exist.
