Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78790, here are decompositions:

3 + 78787 = 78790
11 + 78779 = 78790
53 + 78737 = 78790
83 + 78707 = 78790
137 + 78653 = 78790
167 + 78623 = 78790
197 + 78593 = 78790
251 + 78539 = 78790

Showing the first eight; more decompositions exist.
