Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719770, here are decompositions:

23 + 8719747 = 8719770
67 + 8719703 = 8719770
71 + 8719699 = 8719770
89 + 8719681 = 8719770
107 + 8719663 = 8719770
109 + 8719661 = 8719770
167 + 8719603 = 8719770
179 + 8719591 = 8719770

Showing the first eight; more decompositions exist.
