Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77986, here are decompositions:

3 + 77983 = 77986
17 + 77969 = 77986
53 + 77933 = 77986
137 + 77849 = 77986
173 + 77813 = 77986
239 + 77747 = 77986
263 + 77723 = 77986
443 + 77543 = 77986

Showing the first eight; more decompositions exist.
