Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751864, here are decompositions:

5 + 8751859 = 8751864
47 + 8751817 = 8751864
61 + 8751803 = 8751864
83 + 8751781 = 8751864
97 + 8751767 = 8751864
131 + 8751733 = 8751864
137 + 8751727 = 8751864
193 + 8751671 = 8751864

Showing the first eight; more decompositions exist.
