Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78776, here are decompositions:

79 + 78697 = 78776
127 + 78649 = 78776
193 + 78583 = 78776
199 + 78577 = 78776
223 + 78553 = 78776
337 + 78439 = 78776
349 + 78427 = 78776
409 + 78367 = 78776

Showing the first eight; more decompositions exist.
