Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726874, here are decompositions:

11 + 8726863 = 8726874
71 + 8726803 = 8726874
73 + 8726801 = 8726874
97 + 8726777 = 8726874
113 + 8726761 = 8726874
137 + 8726737 = 8726874
151 + 8726723 = 8726874
197 + 8726677 = 8726874

Showing the first eight; more decompositions exist.
