Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77686, here are decompositions:

5 + 77681 = 77686
113 + 77573 = 77686
137 + 77549 = 77686
173 + 77513 = 77686
197 + 77489 = 77686
239 + 77447 = 77686
269 + 77417 = 77686
317 + 77369 = 77686

Showing the first eight; more decompositions exist.
