Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705748, here are decompositions:

19 + 8705729 = 8705748
59 + 8705689 = 8705748
67 + 8705681 = 8705748
109 + 8705639 = 8705748
131 + 8705617 = 8705748
137 + 8705611 = 8705748
197 + 8705551 = 8705748
199 + 8705549 = 8705748

Showing the first eight; more decompositions exist.
