Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76820, here are decompositions:

19 + 76801 = 76820
43 + 76777 = 76820
67 + 76753 = 76820
103 + 76717 = 76820
223 + 76597 = 76820
241 + 76579 = 76820
277 + 76543 = 76820
283 + 76537 = 76820

Showing the first eight; more decompositions exist.
