Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78782, here are decompositions:

3 + 78779 = 78782
61 + 78721 = 78782
139 + 78643 = 78782
199 + 78583 = 78782
211 + 78571 = 78782
229 + 78553 = 78782
241 + 78541 = 78782
271 + 78511 = 78782

Showing the first eight; more decompositions exist.
