Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739864, here are decompositions:

13 + 8739851 = 8739864
37 + 8739827 = 8739864
41 + 8739823 = 8739864
43 + 8739821 = 8739864
53 + 8739811 = 8739864
61 + 8739803 = 8739864
97 + 8739767 = 8739864
151 + 8739713 = 8739864

Showing the first eight; more decompositions exist.
