Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77286, here are decompositions:

7 + 77279 = 77286
17 + 77269 = 77286
19 + 77267 = 77286
23 + 77263 = 77286
37 + 77249 = 77286
43 + 77243 = 77286
47 + 77239 = 77286
73 + 77213 = 77286

Showing the first eight; more decompositions exist.
