Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77968, here are decompositions:

17 + 77951 = 77968
101 + 77867 = 77968
167 + 77801 = 77968
257 + 77711 = 77968
269 + 77699 = 77968
281 + 77687 = 77968
347 + 77621 = 77968
419 + 77549 = 77968

Showing the first eight; more decompositions exist.
