Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747916, here are decompositions:

13 + 8747903 = 8747916
53 + 8747863 = 8747916
59 + 8747857 = 8747916
97 + 8747819 = 8747916
109 + 8747807 = 8747916
113 + 8747803 = 8747916
127 + 8747789 = 8747916
139 + 8747777 = 8747916

Showing the first eight; more decompositions exist.
