Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77390, here are decompositions:

7 + 77383 = 77390
13 + 77377 = 77390
31 + 77359 = 77390
43 + 77347 = 77390
67 + 77323 = 77390
73 + 77317 = 77390
127 + 77263 = 77390
151 + 77239 = 77390

Showing the first eight; more decompositions exist.
