Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705740, here are decompositions:

11 + 8705729 = 8705740
59 + 8705681 = 8705740
83 + 8705657 = 8705740
101 + 8705639 = 8705740
167 + 8705573 = 8705740
179 + 8705561 = 8705740
191 + 8705549 = 8705740
233 + 8705507 = 8705740

Showing the first eight; more decompositions exist.
