Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8713878, here are decompositions:

11 + 8713867 = 8713878
67 + 8713811 = 8713878
71 + 8713807 = 8713878
97 + 8713781 = 8713878
157 + 8713721 = 8713878
179 + 8713699 = 8713878
311 + 8713567 = 8713878
331 + 8713547 = 8713878

Showing the first eight; more decompositions exist.
