Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77340, here are decompositions:

17 + 77323 = 77340
23 + 77317 = 77340
61 + 77279 = 77340
71 + 77269 = 77340
73 + 77267 = 77340
79 + 77261 = 77340
97 + 77243 = 77340
101 + 77239 = 77340

Showing the first eight; more decompositions exist.
