Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623878, here are decompositions:

31 + 8623847 = 8623878
47 + 8623831 = 8623878
71 + 8623807 = 8623878
79 + 8623799 = 8623878
127 + 8623751 = 8623878
149 + 8623729 = 8623878
157 + 8623721 = 8623878
191 + 8623687 = 8623878

Showing the first eight; more decompositions exist.
