Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77398, here are decompositions:

29 + 77369 = 77398
47 + 77351 = 77398
59 + 77339 = 77398
107 + 77291 = 77398
131 + 77267 = 77398
137 + 77261 = 77398
149 + 77249 = 77398
197 + 77201 = 77398

Showing the first eight; more decompositions exist.
