Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77386, here are decompositions:

3 + 77383 = 77386
17 + 77369 = 77386
47 + 77339 = 77386
107 + 77279 = 77386
137 + 77249 = 77386
149 + 77237 = 77386
173 + 77213 = 77386
233 + 77153 = 77386

Showing the first eight; more decompositions exist.
