Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77310, here are decompositions:

19 + 77291 = 77310
31 + 77279 = 77310
41 + 77269 = 77310
43 + 77267 = 77310
47 + 77263 = 77310
61 + 77249 = 77310
67 + 77243 = 77310
71 + 77239 = 77310

Showing the first eight; more decompositions exist.
