Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83986, here are decompositions:

3 + 83983 = 83986
17 + 83969 = 83986
47 + 83939 = 83986
53 + 83933 = 83986
83 + 83903 = 83986
113 + 83873 = 83986
173 + 83813 = 83986
269 + 83717 = 83986

Showing the first eight; more decompositions exist.
