Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717874, here are decompositions:

5 + 8717869 = 8717874
7 + 8717867 = 8717874
13 + 8717861 = 8717874
17 + 8717857 = 8717874
31 + 8717843 = 8717874
71 + 8717803 = 8717874
83 + 8717791 = 8717874
101 + 8717773 = 8717874

Showing the first eight; more decompositions exist.
