Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78506, here are decompositions:

19 + 78487 = 78506
67 + 78439 = 78506
79 + 78427 = 78506
139 + 78367 = 78506
199 + 78307 = 78506
223 + 78283 = 78506
229 + 78277 = 78506
277 + 78229 = 78506

Showing the first eight; more decompositions exist.
