Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719878, here are decompositions:

5 + 8719873 = 8719878
31 + 8719847 = 8719878
47 + 8719831 = 8719878
59 + 8719819 = 8719878
61 + 8719817 = 8719878
107 + 8719771 = 8719878
131 + 8719747 = 8719878
179 + 8719699 = 8719878

Showing the first eight; more decompositions exist.
