Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78928, here are decompositions:

41 + 78887 = 78928
71 + 78857 = 78928
89 + 78839 = 78928
131 + 78797 = 78928
137 + 78791 = 78928
149 + 78779 = 78928
191 + 78737 = 78928
359 + 78569 = 78928

Showing the first eight; more decompositions exist.
