Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77378, here are decompositions:

19 + 77359 = 77378
31 + 77347 = 77378
61 + 77317 = 77378
109 + 77269 = 77378
139 + 77239 = 77378
211 + 77167 = 77378
241 + 77137 = 77378
277 + 77101 = 77378

Showing the first eight; more decompositions exist.
