Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79986, here are decompositions:

7 + 79979 = 79986
13 + 79973 = 79986
19 + 79967 = 79986
43 + 79943 = 79986
47 + 79939 = 79986
79 + 79907 = 79986
83 + 79903 = 79986
97 + 79889 = 79986

Showing the first eight; more decompositions exist.
