Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79878, here are decompositions:

5 + 79873 = 79878
11 + 79867 = 79878
17 + 79861 = 79878
31 + 79847 = 79878
37 + 79841 = 79878
61 + 79817 = 79878
67 + 79811 = 79878
101 + 79777 = 79878

Showing the first eight; more decompositions exist.
