Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747874, here are decompositions:

11 + 8747863 = 8747874
17 + 8747857 = 8747874
43 + 8747831 = 8747874
67 + 8747807 = 8747874
71 + 8747803 = 8747874
97 + 8747777 = 8747874
127 + 8747747 = 8747874
131 + 8747743 = 8747874

Showing the first eight; more decompositions exist.
