Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80776, here are decompositions:

29 + 80747 = 80776
89 + 80687 = 80776
107 + 80669 = 80776
149 + 80627 = 80776
173 + 80603 = 80776
239 + 80537 = 80776
263 + 80513 = 80776
347 + 80429 = 80776

Showing the first eight; more decompositions exist.
