Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742834, here are decompositions:

13 + 8742821 = 8742834
17 + 8742817 = 8742834
47 + 8742787 = 8742834
157 + 8742677 = 8742834
181 + 8742653 = 8742834
197 + 8742637 = 8742834
211 + 8742623 = 8742834
257 + 8742577 = 8742834

Showing the first eight; more decompositions exist.
