Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78220, here are decompositions:

17 + 78203 = 78220
29 + 78191 = 78220
41 + 78179 = 78220
47 + 78173 = 78220
53 + 78167 = 78220
83 + 78137 = 78220
179 + 78041 = 78220
251 + 77969 = 78220

Showing the first eight; more decompositions exist.
