Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8746878, here are decompositions:

5 + 8746873 = 8746878
17 + 8746861 = 8746878
29 + 8746849 = 8746878
31 + 8746847 = 8746878
59 + 8746819 = 8746878
67 + 8746811 = 8746878
71 + 8746807 = 8746878
79 + 8746799 = 8746878

Showing the first eight; more decompositions exist.
