Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79990, here are decompositions:

3 + 79987 = 79990
11 + 79979 = 79990
17 + 79973 = 79990
23 + 79967 = 79990
47 + 79943 = 79990
83 + 79907 = 79990
89 + 79901 = 79990
101 + 79889 = 79990

Showing the first eight; more decompositions exist.
