Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77388, here are decompositions:

5 + 77383 = 77388
11 + 77377 = 77388
19 + 77369 = 77388
29 + 77359 = 77388
37 + 77351 = 77388
41 + 77347 = 77388
71 + 77317 = 77388
97 + 77291 = 77388

Showing the first eight; more decompositions exist.
