Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77284, here are decompositions:

5 + 77279 = 77284
17 + 77267 = 77284
23 + 77261 = 77284
41 + 77243 = 77284
47 + 77237 = 77284
71 + 77213 = 77284
83 + 77201 = 77284
113 + 77171 = 77284

Showing the first eight; more decompositions exist.
