Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717864, here are decompositions:

3 + 8717861 = 8717864
7 + 8717857 = 8717864
61 + 8717803 = 8717864
73 + 8717791 = 8717864
97 + 8717767 = 8717864
241 + 8717623 = 8717864
307 + 8717557 = 8717864
313 + 8717551 = 8717864

Showing the first eight; more decompositions exist.
