Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701740, here are decompositions:

11 + 8701729 = 8701740
17 + 8701723 = 8701740
31 + 8701709 = 8701740
37 + 8701703 = 8701740
83 + 8701657 = 8701740
97 + 8701643 = 8701740
109 + 8701631 = 8701740
163 + 8701577 = 8701740

Showing the first eight; more decompositions exist.
