Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6878, here are decompositions:

7 + 6871 = 6878
37 + 6841 = 6878
97 + 6781 = 6878
199 + 6679 = 6878
241 + 6637 = 6878
271 + 6607 = 6878
307 + 6571 = 6878
331 + 6547 = 6878

Showing the first eight; more decompositions exist.
