Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76978, here are decompositions:

17 + 76961 = 76978
29 + 76949 = 76978
59 + 76919 = 76978
71 + 76907 = 76978
107 + 76871 = 76978
131 + 76847 = 76978
149 + 76829 = 76978
197 + 76781 = 76978

Showing the first eight; more decompositions exist.
