Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68778, here are decompositions:

7 + 68771 = 68778
11 + 68767 = 68778
29 + 68749 = 68778
41 + 68737 = 68778
67 + 68711 = 68778
79 + 68699 = 68778
109 + 68669 = 68778
139 + 68639 = 68778

Showing the first eight; more decompositions exist.
