Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76878, here are decompositions:

5 + 76873 = 76878
7 + 76871 = 76878
31 + 76847 = 76878
41 + 76837 = 76878
47 + 76831 = 76878
59 + 76819 = 76878
97 + 76781 = 76878
101 + 76777 = 76878

Showing the first eight; more decompositions exist.
