Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78788, here are decompositions:

7 + 78781 = 78788
67 + 78721 = 78788
97 + 78691 = 78788
139 + 78649 = 78788
181 + 78607 = 78788
211 + 78577 = 78788
271 + 78517 = 78788
277 + 78511 = 78788

Showing the first eight; more decompositions exist.
